My sincere condolences go out to the entire Kennedy family, and I send my love during this sad time.
Although I have seen him for a few times, he thought us how to be in a company with passion! Never find in anywhere a best place to work as OSIsoft!

Much condolences to the Kennedy family.

I vividly remember when I first met Pat. He came into the room during my first week of orientation at the OSIsoft headquarter (5450). Unassuming and approachable, yet when you strike a conversation with him, it was clear you were speaking to a real visionary and captivating storyteller. What lingers thereafter was the memory of his faint warm smile behind the white beard and a powerful voice.

Thank you for creating a great product.
Thank you for bringing together a pool of great talents.
Thank you for nurturing a corporate culture that felt like a warm family.

Thank you Pat for the wonderful moments and positive impact you and your company had on my personal life, career and values.

My deepest heartfelt prayers and condolences to the entire family. He created a company like no other. Wishing you peace to bring comfort, courage to face the days ahead and loving memories to forever hold in your heart.

It is with great sadness that I learned of Dr. Patrick Kennedy's passing. During my 10 years as a member of the OSI family, I had the privilege of witnessing firsthand the transformative impact that Pat had on our company, industry, and the lives of countless individuals around the world.

Although I only had a few brief interactions with Pat, his loss feels like that of a dear family member. I know that I am not alone in this sentiment and that many of my former OSI colleagues and customers share my grief.

To Pat, I say rest in peace, and to his family and loved ones, I extend my deepest sympathies and condolences.

Let's start a company and only hire engineers. And we won't waste time with performance reviews, budgets, etc.  And it was magic! 

It worked because PI was great and the employees, motivated by Pat's vision and enthusiasm, were empowered to do anything to help the customer.

Pat embraced my Starbucks addiction and we had many spirited discussions:
- sales force productivity
- real estate investing
- photographic art (Strand, Callaghan, Ragovin)
- War Games, his favorite movie. “A strange game. The only winning move is not to play. How about a nice game of chess?” Pat instinctively applied this famous quote from the movie to stop every knucklehead (like me) from trying to have OSI build applications and sell consulting services.

I’ll always remember Pat as the regular guy with a lousy serve playing ping pong against me at Jenny's house eating walnuts from his tree farm. 

He wasn’t one to brag about his success, but he was a legend on par with Steve Jobs and Bill Gates in our narrow slice of the tech world. I'll never forget this incredible man.

My deepest sympathy to the family.

First, I want to express my condolences to Patty and her family.

There are few words that can adequately describe Pat's legacy. I only wish people understand how his software creation from the early 1980's positively impacts the world today. Are you a fan of clean water and air, fuel efficiency, saving time, and improving operations? Pat had this vision long before anyone cared about environmental management.

His software innovation will continue to make this world a better place for years to come. But his legacy is not just limited to the technology he introduced, he was also an inspirational leader who believed in and trusted his employees. He gave us reign to "spend money like it was our own" and I knew very few people who ever took advantage of him. He was kind and cared about all types of people, he supported DEIW before we ever knew this acronym. I am proud to have dedicated my career to working at OSIsoft. I was employee 35 and headed to AVEVA when we were around 1600 employees. Pat always allowed me to try new things and encouraged my growth and development. He believed in all of us. He cared for us as people and most especially our families. Pat always asked "Are you having fun?" - this was his way of measuring employee satisfaction and engagement and he was right.
I am so proud to be a part of ihis legacy and I look forward to watching his technology continue to positively impact the world in the industries it serves.

Pat hired me 29 years ago. He gave me some words to live by, "Make sure the customer is happy and we can sort out all the other things later." Thank you Pat for including me on this great journey with PI, rest in peace.

Working under OSIsoft culture inspired myself to define and reconsider most of the real value and targets of my professional life. As the founder he was a landmark, a lighthouse and a great leader. I couldn't be more proud to be even a small part of his amazing journey. Thank you !  

"St. Patrick Kennedy" - I remember a former City Manager refer to Pat - not ironically! - in this way once. For the City of San Leandro, his impact on the City's transformation over the past 10 years is immeasurable. I joined the City as its first Chief Innovation Officer -- and the Bay Area and nation's first female municipal CIO -- because of Pat's commitment to OSIsoft and to the City he and Patricia raised their children in. The City's contract with Pat through Dark Fiber LLC led to the creation of "Lit San Leandro" - and the opportunity for OSIsoft and other San Leandro companies to connect to the internet with blazing fast speeds. He also formed a unique partnership with the City by paying for most of my salary for the first couple of years, until the City was able to relieve him of this obligation! If not for Pat's commitment -- and his conviction that Lit San Leandro's blazing fast speeds would be great for real estate investors -- it is likely that San Leandro would still be wondering how to join the tech revolution. Instead, today San Leandro is on the cutting edge of the Industrial Internet of Things - connecting software to hardware because in San Leandro - WE MAKE THINGS. THANK YOU PAT - WE ARE GRATEFUL!

A great man, a forerunner of the times. Thanks to his dream many, like me, have had great working successes with the PI System.


Thanks for everything Pat!

Everyone’s life was better for having known Pat whether they knew him or not. 
Thank you, Pat and your whole wonderful family.

Pat was an incredible help to me when I was starting out with my company. He continued for several years to help me. i so appreciate everything he did. 

Condolences to his entire family. We are sorry for your loss.

Susie Salumunek

My condolences to the whole family and to Pat’s dearest friends. I well remember the early days of market development and the challenges to get all the pieces to work, From the Iso’s at the time , to NERC /FERC having many meetings on the issues with suggested solutions pouring out from many brilliant people , Pat stepped up and delivered . We at PJm were delighted with his work.
  He was definitely a pioneer and a Legend !
Well Done , Pat !

Please accept my sincere condolences on the passing of Pat Kennedy, Founder of OSIsoft, and Chairman Emeritus and most recently a director at AVEVA.

He was an inspiring leader, innovator, and visionary who was passionate about harnessing the power of technology across multiple industries. It was a passion that also inspired a deep and enduring loyalty from all those who worked with him.

My thoughts are with you all during this difficult time.

Caspar.

Really sad to hear, that Pat passed away. Our condolences to the entire family. It was a great pleasure to be part of the OSIsoft family. And I really mean family since it really felt like you were a part of it when working for the company. Pat was a real visionary - really unique.
I always remember when I met Pat and Patty the first time in Altenstadt or having a hallway conversation in San Leandro or even vist Pat at home.
If you would have met him in person, you would never come to the idea that Pat led a very successful software company and also other companies (Lit San Leandro etc.) which were way ahead of their time - really the nice Gentleman next door.

Rest in peace, Pat. We will miss you! But we'll keep your parking lot in front of the SLTC free!

My condolences to the whole family. I still remember meeting Pat at OSIsoft's new hire lunch BBQ for the first time. He was wearing a baseball cap, jeans, and a light jacket. We chatted and I was surprised how down-to-earth he was. Because of this personality, he made OSIsoft a great place to work. He will be missed.

My deepest condolences to the Kennedy Family at this difficult time.

I had the pleasure of meeting Pat a few times in recent years, the most memorable being travelling to dinner across the Bay from San Leandro to San Francisco in a minibus with Pat and some of the team. It was an absolute privilege to hear his stories that night and his insights from the years of building such a successful business have stayed with me. He was a remarkable man and his legacy lives on.

You are a great leader. Your life acheivements inspires us to move forward. May your soul Rest In Peace.

I can hardly believe Pat is gone -- I feel like my Grandpa just passed.

I treasured our 30 minute meetings that often turned into hours-long chats. Pat was an incredible storyteller, and had anecdotes, facts and insights on every topic from the power grid to Australian business culture. He had such a huge heart.
We collaborated on several projects after I joined OSIsoft in 2020, but it was my particular honor to work with him in developing his messages to the customers, partners, analysts, media and employees when he was communicating his decision to entrust AVEVA with carrying on his life's work.

Thank you Pat, and my very best to Patty and the rest of the Kennedy family.

May Pat's soul rest in peace. Very sad news. I met him on a handful of occasions and he always made time to answer any questions I had. My prayers are with him and his family.

I am sorry to hear about the loss of Pat, who was an incredible individual who influenced and changed many of our lives. Even from far away in Brazil, I can see the impact he had on many of us, as evidenced by the messages shared here.

I remember during my orientation week in 2010, when I traveled abroad for the first time, seeing the company organization chart with Pat at the top and everyone else below him. This wasn't because he was superior to everyone, but because he was always open to everyone. He introduced himself to us, new hires, and made it clear that we could reach out to him through email, instant messaging, or even in person (for those working from the office).

From Pat, I learned that no matter what solutions, products, or services you provide, the key is to respect people, understand their needs and pain points, and help them along the way. The most important lesson I learned from him was that money is a consequence and cannot be the main objective.

I am grateful to have been hired to work at his company and to be part of this family that he created. Although I didn't have many opportunities to meet Pat, I did have some quick interactions with him during breaks at events like UCs, Ambassador's workshops, SKOMs...
Despite our brief encounters, Pat's beliefs were so ingrained in the company culture that I felt as though I met him many times.

May he rest in peace. My sincere condolences go out to the entire Kennedy family, and I send my love during this difficult time.

Dear Mrs. Kennedy, Jenny, Kathy, Martin and Mike. My deepest condolences to you and your family. May your family's and Pat's loving memories give you strengths to get through this tough time.

Sincerely,
KimThu

It is with a heavy heart that I learned of the passing of Pat.

Like all of us, I always had a lot of admiration and respect for Pat, beyond the legend he is in technology and our industry.

I was lucky to spend time together in numerous and regular meetings in the past three years, and each of these discussions were both warm and stimulating, often challenging for the mind. They helped me discover OSIsoft and the Man: his deep knowledge, his grounded common sense, his unconventional leadership, his passion for everything - particularly customers-, his attention to people, and his unalterable sense of humor and optimism. I had also discovered and scratched the surface of some of his multiple passions and skills, and his inextinguishable curiosity.

I have learnt so much from him, and I hope we have integrated all the lessons and principles he wanted us to understand. I feel lucky I have known him. We also all feel immensely responsible for bringing his legacy and his principles to the next level.

I am thinking of his family , and all of our colleagues from OSIsoft who have grown with him, and wish them courage in these difficult moments.

I'll keep in mind this huge painting of him at the entrance of San Leandro's building. It is a great art representation of who defined the soul of OSIsoft, a spirit that will keep developing at AVEVA and Schneider

We all have to go at some time but not Pat. When I first moved to the US I was all alone and Pat took me in as a father, a friend and mentor. Pat's passage has left a huge void in my heart. I will always remember and forever miss him.
He was a father figure to many around the world.
Patty, Kathy Jenny, Mike - I am so devasted by this news. My prayers wishes and condolences to you and your families.

As an OSIsoft employee, I had the chance to meet Pat for the first time right after I was hired, traveling across the ocean for the OSIsoft welcome week. 2nd day of that week, Pat shows up to have lunch with all the new hires, sat at my table and we had the most casual and random discussions (young me thinking : "wow my CEO is so easy going"). Later in the day, Pat talked to all of us about the company, his vision, and it was getting clear for me I just landed in a unique company founded by a passionate man.

Over the years, experiences and discussions about the working life, it is astonishing to see the culture, collaboration, sense of belonging and motivation developed in OSIsoft under the leadership of Pat.

He is a leader so many others should learn from, he created a company so many others should strive to equal.

All my condolences to the family.

Dr. Kennedy,

I wrote 26 thank you notes this past year as I rode my bicycle across America for St. Jude Children's Research Hospital. I beat myself up a little everyday for not thanking you. We only met once, as I worked for the family of OSI for nearly four years, half of it during COVID. When you announced the sale of the company, you found a way to take care of all of us with a token of your gratitude. To us, it was much more than a token. In a way, you financed my trip across America, and I paid your generosity forward to St. Jude. You made a difference in my life and you supported me to make a difference in the lives of kids with Cancer. Others can speak of your leadership and innovation. I can attest to your kindness. Thank you, sir!

Go n-éirí an bóthar leat chun bualadh leat.
Go raibh an ghaoth i gcónaí ar do dhroim.
Go lasadh an ghrian te ar d'aghaidh;
Titeann an bháisteach bog ar do pháirceanna agus go gcasfar le chéile sinn arís,
go gcoinní Dia i dtearmann a láimhe thú.

While I’m still in shock and saddened about the loss of Pat, I would like to share some stories that I will forever remember and cherish. Like Pat, he always liked to tell stories.

My first OSIsoft Users Conference was in 2002 in Monterey, CA, as a customer. I was so impressed and inspired by all the happy and smiling faces. Before I knew it, I was on stage sharing the good stories of PI. After my talk at 2004 UC, Pat came to me saying “I really like your talk”. I asked, “what do you like about”? Pat said one word, “enthusiasm.” I said “how can we not love PI? In 2006, I joined OSIsoft and became part of the OSI-family and Pat called me an “evangelist”. My passion and belief, the love of the product, our customers, and the company, have been growing even stronger since. Pat created an amazing product and an amazing company, with loyal and appreciative customers all over the world.

Some of the conversations/talks with Pat throughout the years that I still remember clearly as if it were yesterday…just a few examples…

- I need to have the right direction and vision for the company, because so many people (employees and their families, customers and their families, partners and their families, etc.) will be affected by any decision I make.

- "We sell what we make.” - Be honest, don’t lie or cheat to get the deal. I don’t want that money; I would rather you walk away. Don’t jeopardize your job.

- One time at a customer event, customers asked Pat, why not making PI as a SCADA, all you need is control. Pat said, why do I compete with all the SCADA vendors? Now I’m working with all of them.

- When a lot of electric utility customers started implementing PI-based CBM (Condition-based Maintenance) about 15+ years ago, we wrote a step-by-step blueprint as an implementation guideline. Customers asked Pat, why not packaging CBM as an “Application” (at that time, we all tried to avoid this “A” word). Pat said, I have eight different industries, every industry has different requirements, why should I develop eight solutions? Now I offer one product and every industry can use it to develop it.

- One day Pat saw me in San Leandro office and asked, “why are you not traveling?” I said “Pat, it’s the end of the year, most customers are off for the holidays.” Pat said, “Then go to sell in China or in India.” I said, “Pat, I am not in sales.” Pat said, “Either you make, or you sell. Everyone here sells.”

- Pat never used PowerPoint slides for his talks. He said, “If you don’t use slides, people focus on what you say, with slides they focus on what you show on the slides.”

- Pat remembered every customer’s presentation down to details, especially from the electric grid. On many occasions including recently, he mentioned the story about when Hurricanes Gustav hitting Louisiana, how Entergy using PI and PMU synchrophasor data to detect and manage the islanding in New Orleans and seamlessly restore and resynchronize the system. The islanding event happened in 2008! It's because Pat cared!

It’s still shocking and heartbreaking to me of Pat's passing. I am very thankful for all the support from Pat and family.

My deepest condolences to Patty, Jenny, Kathy, Mike and the family.

From Ann

wonderful visionary to introduce a product like PI system. Entire industrial world across the globe are successful in producing something better. Pray god to give required strength to his family. world has missed a great personality

一位慈祥的老人，愿他在天国中永生！
永远是我们心中的老 Pat！

Pat was the most important person in my professional career. I decided to change careers from a chemical engineer to a software engineer in 1992. I came across a small ad in the San Francisco Chronicle--a company was looking for chemical engineers that could program. What an odd perfect fit. That company turned out to be Oil Systems, Inc.

A few days later I spent a day of interviews wrapping up in Pat's office. Pat and I spoke for two hours. I cautioned Pat that I was not a professional software person yet. His response was confident, understated encouragement. He had great company in place with great people. I knew then I'd be working for Oil Systems.

Pat started Oil Systems before software companies were a thing. I was a technical guy and new little about business. It was fascinating watching a very technical person, and more importantly a real business person, navigate the rapidly changing software business. His company lived through major shifts in the software industry and Pat successfully manage Oil Systems through these changes. Renaming us to OSIsoft reflecting our position as a pure software company, and the leading industrial software company.

Pat's company created an important product that helps most of the major manufacturers in the world. The products help these companies run their business more efficiently, safer, and environmentally sound. The products make the world a better place. The OSIsoft products lead to a large ecosystem of products, companies and cooperation with industry. Pat and OSIsoft positively influenced countless people, careers, and companies.

Hardly a working day goes by for me without using the lessons I learned from Pat. I think about Pat and my great experiences working for him and OSIsoft often. I've been doing my best to pass some of this wisdom to my work colleagues. I will miss Pat.

My condolences to Patti, Jenny, Mike, Kathy, and the rest of the Kennedy family. Thank you for allowing me to be a small part of your family. Rest in peace Pat.

Jon Peterson

It was with deep sadness to hear the news of Pat’s passing. My heartfelt condolences go to all your family. Pat will be sorely missed; he has had a positive impact on so many people over the decades both professionally and personally.
I will always remember Pat for being a great business partner, a mentor, colleague and a friend over the time we worked closely together. In the last years we have been talking almost on a weekly basis and he helped me to deeper understand the PI system, the colleagues of OSIsoft, the spirit under which he had built the company and principles which had guided him. I will miss you and rest in peace.

I am thinking of you all at this difficult time.

Peter Herweck

A giant in the industry. A decent man.

I am very sad to learn of Pat’s passing. He was one of the most insightful leaders I have known. His wisdom and influence on industrial data technology will be remembered forever. I always listened to every word Pat said. He had a huge impact on industrial technology and industry, and will be missed by all.

My condolences to the Kennedy family for their loss. It was shocking learning of his passing and a lot to process. I didn't know Pat very well personally but, after working at OSIsoft for over a decade, I felt like I knew him based on the company he cultivated and the people who worked here. I've made life-long friends at this company, and I think that's a testament to the kind of close-knit community Pat built. Thank you, Pat, for your years of dedication to us and making it a great place to express ourselves and pursue our passions.

I was deeply saddened to hear about the loss of Pat. I was fortunate to meet him when I had just started at OSIsoft.

Pat, you left us too soon! You will forever be in our minds and our hearts.

My condolences to Pat's family and friends.

R.S

I met Pat in the twilight of his career when I came to OSIsoft. I saw immediately how Pat embodied the company’s mission. Pat built the customer base that anchors our businesses today. My thoughts are with his wife and family for sharing their dad with us for 40+ years. My thoughts are with everyone at AVEVA working to continue Pat’s work.

Forever in my heart.

It is so sad to lose such an extraordinarily person. I still remember meeting Pat when I started my journey at OSIsoft about 12 years ago. Back then, work was also family because of Pat's energy and vision for the company.

Pat, may your soul rest in peace. Love, Karim.

Think of you Pat

I was very sadden to have learned yesterday of the Pat’s passing.

I had the great pleasure of getting to know Pat, his family back and his company OSIsoft with I worked for the Utility TransAlta way back in 1999.

I learned so much from him and OSIsoft was one of my first clients when I first started my company KurMeta in 2005.

I am forever grateful for his kindness and support over so many years. It was thanks to him and OSIsoft that I had my first opportunities to travel throughout Asia at many OSIsoft events and meeting so many OSIsoft clients around the world. Many of which became friends.

I so remember Pat’s passion for applying OSIsoft’s software in so many different use cases especially Energy Management.

I was grateful to have had the opportunity to collaborate together along with Vivek Bapat on the book “In Pursuit of the Perfect Plant” back in 2008. It was an idea I came up with that Pat jump on board to participate as did Vivek. 

My deepest sympathies go out to his wife Patty and the rest of his family at this difficult time.

I will miss you Pat, rest in peace, you have made a difference and have impact many.

When I starter working with OSIsoft 10 years ago, I was really surprised with the passion customers talked about PI and OSIsoft.. as a new person at that time, they were selling PI to me! That gave me an idea of the amazing person behind the company, Pat Kennedy, and journey to come.. a fantastic one.
Pat created a wonderful company, a family, that provided us a chance to learn, to grow as a professional and as a person; a place to meet such a great group of people, many of them dear friends. I thank the opportunity he gave us to be part of his dream..we will always remember you as a pathfinder and example to follow.
My deepest condolences to the Kennedy family. Hope these stories we share today will provide some comfort.
Rest In Peace.

科技造福人类，江湖上永远的传奇，没有数据，就像无源之水。感恩，怀念，一路走好。

My deepest condolences to the Kennedy family. Pat was my mentor and I love contributing to his vision and writing about PI. I am really choked and I will miss him. Prayers and Rest with PI in the sky.

Our heartfelt thoughts are with Patty and our Kennedy cousins. Our family has always been so proud of Pat. Our grandfather, Ralph King, Sr. was so impressed with his engineering acumen and was proud to have him with him at his company in Arkansas for a time when he was a student. I remember Pat and his brothers as "California Dreamers". Very recently Pat supported our efforts to preserve a Civil War era Kennedy family cemetery that was damaged in a tornado. This will greatly increase our chance of success with this project. Pat was always so patient with my many questions. We enjoyed the family visits in Kansas and our lunch outings on trips to San Leandro. I guess when you combine Celts, abolitionists, Quakers and strong German mothers and grandmothers, great things can happen! We will miss Pat. As always, I'm signing off with love and sunflowers. Ruth Anne

My condolences to the Kennedy family.

“ I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel”

Thank you and Rest well, Pat.

Pat created a unique product and unique company that gave an amazing chance to so many young specialists to grow, learn, travel the world, and meet incredible people.
Many of us owe him our careers, our work friends, our knowledge. We will all be always grateful.
Thank you, Dr. J. Pat Kennedy. Goodbye.

A great man.
A great product.
A great company.
A legend.

I really feel honored had a chance been an employee in OSIsoft, a real family to everyone of us.

Dr. J. Patrick Kennedy will be missed but never forgotten.

OSIsoft and more specifically Pat Kennedy was a brilliant and approachable person. As an old employee I’ve to say thanks for all the great moments I’ve experienced. I’m sure the memories will stay alive forever and wish the Kennedy family my condolences. Keep the memories alive!

During my 11 years at OSIsoft, I had two families. It was special and unique and it was all built by Pat. He cared about us and our customers like family and yesterday I lost a family member. I grew up with PI and believed in it just like Pat did , and I feel honored to have shared the passion and love for it with him. i always recall Pat quizzing me once on what was more expensive In Saudi, Water or Oil?! I had never thought about it before but the answer was definitely Water! We lost an extraordinary man, may he rest in peace.

"As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them." JFK

Thank you, Dr. J. Pat Kennedy.
My deepest condolences, love and light to the whole family.

Pat was a nine-sigma guy. Few of us are lucky to meet his equal over a lifetime. His word was his bond. Technical genius. Employees stayed for a career. Customer satisfaction as you've never seen before. Behind-the-scene personal support for those in need. God bless you, Pat

Dear Patty, Jenny, Kathy & Mike,
Please accept my deepest sympathy on the passing of your beloved husband & dad. I loved Pat. Heaven certainly gained an angel. Know of my love & prayers for all of you at this time and always.
