So very sorry to hear of this wonderful teacher's passing. I had the pleasure of attending his class while he taught at Foothill in 1987 and enjoyed his class immensely. In fact it was just last week I took my kids on a bike ride around the neighborhood and stopped off at Foothill and showed them the classroom where Mr. Thiel taught me many years ago - just that one classroom. My thoughts and prayers go out to his wife and children.

This is such sad news. My thoughts and prayers go out to Eric's family and to all of his former students. He was the guy to go to if you wanted to know what was going on 'down at the creek.' Pleasanton will miss you Eric.

I was an AVHS graduate of 2000. Although I never had the pleasure of being in his class, I knew his name from friends and I knew that he was a coveted teacher! This is very sad news, and I am sorry for his family's loss. Rest in peace.

In shock. What a great example of leadership he was. Such a great human being. My condolences, my heart needs repair.

RIP Mr.Thiel !! He was an incredibly fun and kind teacher ! I had the pleasure of being in his biology class @ Foothill in 1991 -

What I Remember about Mr. Thiel,

*I remember being in the first class he taught at Foothill High school, back in the dinosaur days.
*I remember him being much younger than most of our teachers,
*I remember his being nervous on that first day,
*I remember him being kind & tolerant of student antics.
*I remember him being funny and enthusiastic about science.
*I remember that even if you weren't a big "biology" fan, you never minded going to his class, you were guaranteed a teacher who tried to make you laugh, while driving his points home.
I remember Mr Thiel as being a fun teacher who cared about the students he held responsibility for.

I can honestly say, I don't remember a lot about the subject matter. It's funny though, this past school year, I was reviewing paperwork with my 14 year old son for an upcoming science test, and I was surprised at how much I remembered about plants, and amazed at how much we have learned in the intervening years. DNA wasn't even mentioned when I had science class.

In reading the comments others have left, I can only imagine how excited Mr Thiel must have been with the knowledge humanity has gained in leaps and bounds over the last 30 years. I would be willing to bet that each new school year offered him so many more options in sharing new information with his students and I am certain, this only added to his enthusiasm.

I am not at all surprised that he took his work outside of the classroom and into the community.

I am deeply saddened to learn, after all the time he gave to others, he has been robbed of the opportunity to share his time more freely with his loved ones upon retiring.

I can only hope that learning of the impact he had on so many lives brings some measure of comfort to his family.

I confer many, many kudos to the student who picked him to visit the White House and meet President Obama. I cannot think of a more deserving person to share in such an honor.

I can't really put into words how I feel about this tragedy and tears don't fit on a computer screen.

I can only say that Mr Thiel was one of kind, my heart goes out to his family & friends, he will be sorely missed by so many. Humanity needs people like him, and his loss is a loss to us all.

RIP Mr Thiel - I hope someone with as much humor and compassion will step in to pick up where you left off........

Deepest sympathy and prayers for his family. Both of our boys had him for Biology and AP Biology at AVHS. He was inspirational and did a great job of preparing our boys for college level science.

Eric and I grew up together in the Oakland Hills and were best of friends thru school. I always knew he was a special individual destined to make a positive difference in society. I am saddened by his death and the fact that we grew apart and lived our lives out without maintain our friendship. RIP good buddy and see you again down the road!

I was at Foothill in the late 80's. Eric was truly the best of the best. I was his guinea pig and did an independent study AP bio class with him as an elective as the only student. I was his TA and helped him set up his grades on Excel.
I played gin rummy with him as a TA as a senior, and rarely won. I was a biology major in college. My niece has him as a teacher as well and she is now a biology teacher herself. No teacher in my life had the impact on my life as he had, and I hope his family knows how much he positively affected the world thru his teaching and inspiring so many students
