I am sorry to hear the sad news. I am an ES graduate from 2009 and now I am about to begin my master's thesis on the double diversion in a few weeks...Professor Freudenburg loved the idea when I emailed him for advice about it, I'm sorry he won't be around to read it, but I'll work extra hard on it to make him proud! thanks for all the inspiration Professor

"BBB" -- Big Brother Bill -- thanks for the wisdom, the joy and the humor you brought to our lives! And students -- thank you for sharing a side of Bill's world that the family didn't often have a chance to see.

Bill Freudenburg was one of the kindest and most approachable professors I had in my time at UCSB. I feel fortunate to have taken ES1 honors my first year, where he inspired me to think deeply about and challenge many things I accepted as a normal part of life. I will always remember the picture he showed of a $2.50 bottle of Evian water next to the tap in his hotel!
Rest in Peace Professor

Bill, I didn't know you very long or very well, but I so enjoyed your company. I miss your (sometimes) wicked sense of humor and your ever present smile. Peaceful journey.

Bill, your smile, wit, passion, humor and friendship will never be forgotten. Your friend forever!

Bill was the most inspirational professor of my tenure as a student. He frequently extended great acts of kindness towards his students, and his only expectation was that we do the same for our students when we are able to. In a large public university, it is very rare to find a professor that makes as sincere of an attempt to get to know and befriend students as Bill did.

In the simplest words, Professor Freudenburg is the reason I became an Environmental Studies major. His undying passion and truly inspirational lectures re-awakened a passion of my own as a freshman and changed the course of my educational career, and in turn, my life. It is with great sadness we see him go, but in his memory that we continue to forge the path he began for us all.

Bill was SUCH a joy to be around. I feel blessed to have met him and spent time with him. His passion for environmental issues, for people, and for academia always felt so blissful and genuine. He inspired me, as I'm sure he inspired so many others. His life was one that touched and changed more than he could have imagined.

Prior to taking Professor Freudenburg's class I had no passion towards any particular field of study at UCSB. With a single lecture Professor Freudenburg had me hooked on environmental issues and his theory of 'double diversion.' Thank you, Professor Freudenburg, for all that you have contributed to my life and to those of others.

I was a student of Bill's in 2006. I wrote him an email at the end of the quarter letting him know how much I enjoyed his class and he wrote back this,
Thanks very much --It's working with positive students like you that convinces me I happen to have the best job in the world.
All the best -- Professor Bill

Best professor I've ever had. His passion for his work brought me to tears some lectures. I am so thankful for being able to hear him speak.
I believe many of his students will never forget his words and go on to change the world they way he would have hoped.
You will be missed

Professor Freudenburg reaffirmed my passion for environmental studies with his incredible Env S. 1 class. He would lecture for an hour and ten minutes, and then in the last five he would make his point, effectively turning my and every other students' world upside down. To this day he is still the only Professor I have had who received applause and ovations after every single one of his lectures.
