I share Cassie's tributes. My brother, John, was always so tolerant of his "dumb" sister (me) and taught me so much. He constantly inspired me to continue to love classical music and he was the family genious. He will always be so missed!

Thinking about John today, and how much he meant to me and all those fortunate enough to know him. He was such a kind person, and generously shared his knowledge and passion for the things he loved. He made the world a better place.

I'm headed to SHARE next week where John made a significant impact and his memory will live on. He remains an inspiration to many (especially me).

Dearest John,

Even though we were together for 35 years, today is our second wedding anniversary. Such a beautiful day, and although you were so sick, you were a super trooper. Sadly I had to lose you five days later, however, for you it was the best. As you kept telling me "it is all in God's hands"
Today I will have lunch with Anne Teng, at our favorite place Brian's, now The Bell Tower. This evening I go with the Sterks to Bing at Stanford to hear Mozart's Requiem plus one of the Brandenburgs. 
Every Monday evening I help with the Schola Rehearsal break refreshments. Always good to see some "old timers".
I miss you so incredibly much. Still go to counselling with a wonderful and sweet person. 
I love you to the moon and back and promise to write more.

I knew John as a fellow member at Palo Alto Christian Reformed Church while working for a start-up company in Sunnyvale, California from May 2011 to June 2013 and then from Nov. 2014 to Sept. 2015. He had a kind and selfless disposition and occasionally conducted the choir at PACRC. I did not know he was so intelligent and took credit for writing a high level assembler language. I can relate because writing an assembler for the IBM 370 mainframe was one of my projects during my fourth year of undergraduate studies in computer science at the University of Ottawa in Ottawa, Canada in 1984. My sincere condolences to you Tineke. Your husband fought a courageous battle with cancer, lost the fight, but now is rejoicing with God's angels in heaven. Until we meet again!

Congratulations dearest John,
I just received notice that yet another patent was approved in your name!
Although you are the most humble person, I do like to share this with all who read this.
My forever love! Tineke

Dearest John,
Happy 83rd Birthday! A sad day to say the least :-( although yesterday was more difficult as on the fourth we, the Dutch Bunch, always celebrated YOU with a barbecue at the Olthofs.  Not this year, mainly due to several folks being sick....Instead the DB friends joined me this evening for toasting you and share memories. It was strange not having you in our midst.
Rest in peace my dearest friend and husband, or as your mother would refer to me as "my son's spose" meaning "suppose they'll ever get married?"
I have posted a picture of your special home memorial, complete with lighted candle. 
Forever loved by me!! Tineke

My heart is heavy and filled with sadness for the loss of such a kind,
gentle, and courageous man. I worked with Tina many years ago at
SLAC and only recently met John at Palo Alto Medical Foundation, where he
had been a patient. I just learned of his passing one week ago from a
mutual friend. I am comforted that he had the best attention from his
loving and kind wife. They were a special couple. He will be missed by
everyone who knew him - what a sweet smile!

Dearest John,
It has been nearly four months since your passing, yet it still feels as if you are "just on a one week SHARE trip". On May 5 we had the most beautiful memorial service, complete with all the J.S. Bach music you had chosen.
Rest in Peace most wonderful person, and sing with angels. They can always use a good DEEP bass voice :-). All my love, Tineke
In his prayer Pastor Dan Hutt said "May we have the courage, as John liked to quote, 'to comfort the afflicted, and to afflict the comfortable' "

I knew John at the IBM Santa Teresa Lab from at least the 90's.
He had a calm, quiet, confident - and above all - correct authority which surpassed the noisy climbers in every way.
He is among the most respected people that I have known, and I am better for knowing him.
John - from now on, may all your return codes be zero.

My wife Anna and I ran into John and Tineke in Carmel last July while they were attending the Bach Festival. I worked with John at SLAC for many years before he moved to IBM. Those were fun times. I also ran into him frequently when I moved to IBM myself and at countless SHARE meetings. Anna and I even cataloged his contribution of Assembler language memorabilia to the Computer History Museum!

Good bye John, it was good knowing you!

John has been gone about six weeks. Exactly one month from today, April 5, will be John's Memorial/Celebration of Life. I so look forward to the J.S. Bach music which John selected; the words spoken by his nephew and friends John selected. John deserves nothing but the best, knowing how humble he was and hated it when folks placed him on a pedestal...I so miss his quiet demeanor, his loving kindness, and patience. May he rest in peace. As it states in one or our church hymns "EARTH HAS NO SORROW THAT HEAVEN CANNOT HEAL". Rest in peace dearest John. Your loving wife, Tineke

Memorial/Celebration of Life:

When:  Saturday, May 5, at 10:00am
Where: Sunnyvale Presbyterian Church, Fremont Avenue, Sunnyvale.
Music:  Mostly J.S. Bach, as chosen by John.

All are welcome!

I met John somewhere back in the late 80s when I was working in Fortran at what was then the IBM Santa Teresa Lab (now Silicon Valley Lab). I could see right off how sharp John was technically but what struck me was how approachable and personable he was. Very easy to talk to and always willing to share his knowledge.
I think my fondest memory of John happened in a large meeting with many managers and technical folks. The topic was how we approached customers. John got up, put his hands over his eyes and rolled his head around, saying that all too often IBMers would go to customers and act like they had blinders on. I nearly fell out of my chair. A lively discussion followed. All initiated by John's wonderful wit and humor. He will be greatly missed.

During my considerable years at STL working on various compilers, John always seemed to have an office nearby. He was always available to answer a question, offer an explaination (he just loved slipping into “teacher mode”) or help solve a problem. Many a project were completed because of his willingness to put his own work aside so that we could take advantage of his HLASM expertise. John was the perfect teacher, mentor, leader.....calm, knowledgeable, easy going and could explain the most complex idea in terms that the rest of us could understand. He had a wonderful career at IBM and I am thankful that I had an opportunity to work with him.

John and I put together the "Assembler Indignaiton" project at GUIDE user group. The GUIDE management thought there was no interest. John and I proved otherwise. If I suggested a topic for "next meeting" John could always come through. I enjoyed working with him at GUIDE and SHARE. John's good humor and skilled teaching will be missed.
Posted by Nancy Wheeler on March 21, 2018
I came to know John at SHARE when I was assigned to be the IBM representative for the APL project in the late 1980's.  He was a mentor to me there, and through the years was always available to help with the tricky stuff like machine architecture and most recently, helping me understand complex numbers.  About a year ago he took a group of us on a tour of the Computer History Museum which was completely fascinating. I will miss his kindness, keen intelligence and dry sense of humor.
Posted by Joan Alter on March 20, 2018
I have fond memories of John from SLAC in the late 60s. I learned assembler from an early draft of his textbook, printed on computer paper. He was a wonderful mentor and extremely witty.
Posted by James Dargin on March 20, 2018
RIP John.

I met John when he was assigned to the IBM repository
project as the Languages/Assembler representative.

He was always so positive even though skeptical -- fun to be around.
In later years he was a regular at the SVL cafe at a table where deep conversations could be joined.

He will be missed.

I was a colleague of John's at SLAC in the early 1970s. We shared a fondness for IBM 360/370 assembly-language programming and a love/hate relationship with IBM. I lost touch with John when i moved to a small start-up company in San Francisco, but found him again when, back in Silicon Valley, I began participating in Schola Cantorum's Messiah Sings. Lo and behold, there was John, helping me track Handel's bass parts! Thanks for showing me the way, John. Like you, I'll go on singing as long as I am able.

I suspect I first met John in 1990 which was my first year doing the Carmel Bach Festival. Being new and not knowing anyone, I remember feeling rather lonely. After a tower music program, John singled me out and started a conversation including questions about instruments and music. He was also very complimentary of my playing which of course I appreciated.
One year John and Tineke invited me to lunch with them at the Little Swiss Cafe, which became an annual ritual. We’d have a lively conversation, including festival gossip, and examine the ever changing artwork in the cafe.
John and I corresponded once or twice a year. Even after I left the festival after 20 years, he didn’t forget me and continued to write, never mentioning his illness.
He was a kind man, thoughtful and ever curious. I will always remember him with love.

We will always remember John for his kindness, his passion for life, and his eternally boyish smile. He enriched our lives with his deep knowledge on a wide variety of topics and his desire to share the activities he loved. He shared that knowledge and those activities freely with enthusiasm. His passion was infectious and it added to the enjoyment of spending time with him at meals or concerts or lectures. John always had some little known fact to add that made you feel like were in on a secret. He approached life with such joy; he knew what he wanted to do and nothing would stop him. He relished bringing people together and everyone was treated like family. John added to the texture of our lives and will long be remembered with love and respect.
Posted by Dee Hartzog on March 3, 2018
John, my brother, was 2 years older but many years smarter and always tolerant and helpful. He helped me struggle through understanding physics in high school and introduced me to the Bach Festival in Carmel and the Messiah Sing Along, as well as the Schola Cantorum. He was so special and will be missed forever.

We met our dear friend, Tineke, in 1969. It was much later when we met John on several trips to California. Living in Western NY, we didn't get to that part of the country often, but it was a delight to spend time with the two of them when we had the chance. It was easy to feel the love they shared for each other and complemented each other. As Tineke would update us on John's medical issues, we can agree with the friend, Ed, who labeled him the "energizer bunny." Now he is resting in peace. It's sad to know we won't get a chance to see him again but blessed to have crossed his path.

I credit my Uncle John with getting me interested in computers, from the tours at SLAC and the ascii art he printed for me there, to the computer games he let me play on his home terminal, to helping him assemble a computer terminal from a Radio Shack kit, and teaching me the basics of programming. Later, he arranged an internship for me at IBM. I enjoyed sharing his delight in computers at the Computer History Museum. I am proud that some of the handheld devices I worked on are in the museum, alongside the mainframes he cut his teeth on. In this, and in many other ways, he enriched my life, which is the poorer for his passing.

I worked with John in the 1980’s at the Stanford Linear Accelerator Center. John was always such a calm, solid presence. In addition to knowing his stuff technically, he just knew what he was about. Layered on top of this competent, confident man was the most delicious wry sense of humor. He was always good for a lively conversation and a good laugh. He made the world a better place and will be sorely missed.

I worked with "Dr John" at IBM at the STL facility for many years. I watched John and viewed him as my role model - extremely smart, innovative (before the term was in vogue), always calm and well-mannered in all situations, and above all willing to help. He had the 'professor' in him that made him a natural teacher and took the time to explain things. He loved talking about technical things (assembler!), but he also took the time to explain things to me about the business side of IBM. I learned so much from John that it is truly hard to quantify. I will always remember him and speak of him fondly.
Posted by Ed Oddo on February 28, 2018
I worked with John for many, many years at IBM. I remember the "Dr. John" posters scattered around the SVL (aka STL) lab years ago. The expression on John's face in the picture on this site captures his essence. I never knew him to complain and his demeaoner was always the same, calm, cool and collected and his wry sense of humor ever present. He seemed to have more than his share of physical challenges over the past decade or so and I came to liken him to the energizer bunny --- takes a licking but keeps on ticking. He will be missed and remembered for sure.

It is with great sadness that my husband John Robert Ehrman passed away just two weeks after having been told that the bladder/prostate cancer had practically exploded to liver and kidneys. Three months was the word, however, John was relieved of his shut down body just two weeks later. His mind, however, was just as sharp as ever.
I shall forever love and miss him.

I will always remember John Ehrman as the father of IBM High Level Assembler. We met many times at SHARE where he managed the Assembler Project. He was passionate about everyone learning assembler and enjoyed teaching classes.

I could always ask john a question about HLASM via e-mail and his first response was,,, Read the Documentation and reread it again,,, then he would always include the solution i was seeking... It always seemed that he knew that I was using it for

Dearest John,

It has been far too long that I wrote you a note.  This of course does not mean that I have forgotten you, as that is simply impossible.  Luckily you know me well enough to realize that I kept putting it off, being the forgetful person I am.  But enough about that.

I still go to counseling, one on one, once a week with an incredibly kind and understanding "youngish" woman I met through Pathways, andis now with Kara in Palo Alto.  

Almost every Monday evening I attend the Schola rehearsal for just a little while.  I help with the refreshments, visit with folks, stay for an adidtional half hour to listen.  Carol Worthington-Levy and I sponsor the Christmas concert!  The fall concert was Duke Ellington gospel music, with a complete jazz band.  It was really nice.  You would have loved it.  So far I am not too enthused about the Christmas concert; as always it has to grow on me, ahem.

Schola "lost" about 18 members, but they gained 14 new ones.  No re-auditioning was required.  Such will be next year.  I really like the new conductor.

The Sterks have once again invited me for Thanksgiving dinner.  Valerie's parents will be here again, as the SVPC Christmas concert is December 8.

I miss you tremendously; still have moments that I think you are coming home.  Often I can't wait to come home and share something I have noticed on the way, or tell you something interesting I was told.

I love you and always will.  
As I said before "I love to Heaven and Back"



One Year Death Anniversary

Shared by Tineke Graafland on February 26, 2019

Dearest John,

A year has passed since God called you home on February 20, 2018.

Anne Verweij was here for the week and helped me get through it.  In the morning Pat and Pietie came for coffee.  Early afternoon Anne and I drove to Milbrae to take BART to SF in order to meet her cousin Jitske, second daughter of Jeanette Boonstra, who is a co-pilot for British Air and in town for a day.  We got off at the Montgomery station, where Jitske waited for us in a bright red coat, so we could not miss her :-).  The weather was sunny but quite breezy and cold.  We walked to the Ferry Building, which I had not seen inside.  From there we walked to the Pier 23 Cafe and had a wonderful fish and chips "dunch".  Then on to Pier 39, which is not nearly as fun as before as high end shops are coming in.  At least the seals were presen, haha.  The gals then introduced me to Uber, which we took to the Castro, where we had drinks in a delightful corner bar.  Uber back to the Park Hotel where Jitske was staying, one block from the Montgomery station, where we took BART back to Millbrae.  Earlier when I parked the car a gent walked up to his car next to mine and gave me his paid parking ticket. Not too shabby, huh?!  The gals kept me busy so that I was able to take my mind off the day.

There is so much I wish I had been able to share with you before you died. Even apologized for, but you went so quickly.  Know that I love(d) you with all my heart and being.  You are definitely one in a million.

Rest peacefully my Dearest...All my love, TinekeG :-) 

Oh yes: unbelievable the destruction on the Capitola beach, and the Carmel beach from an earlier storm. The latter doesn't even look the same.

Our Wedding Anniversary

Shared by Tineke Graafland on February 15, 2019

Hello dearest husband of mine (:-)

You have not heard me for some time (at least on this tribute) but as today is the first anniversary of our wedding I want to reiterate how much I love you and what you meant to me over the many years we were together.....Joan Sakaldasis is taking me to lunch, and this evening I go with the Sterks to Stanford to listen to Durufle's Requiem.

You may like to know that I bit the bullet and ordered tickets for the Carmel Bach Festival, and made reservations at the Lobos, but NOT our room of many years.

 Next week already one year since God called you home. Oh, how I miss you :-(

Rest in Peace!!....Tineke

PS: I forgot to say that yet another patent (group) was approved (:-)
