Donald Leibowitz

Here we are again Don, another year has passed. Just want to let you know you are not forgotten, old friend.

Nine years already. Still miss you Don. One of my favorite people on the planet.

Here we are 8 years later. Still hard to believe you're gone. You were a great friend and teacher, even though I never really got the concept of calculus!
Goodbye again old friend. Miss you. ❤

I was lucky to have been made a better person through Don's mentoring. I will remember most his quick wit, passion and impeccable character. The world is a lesser place without him.

Don was instrumental in our developing the first new district energy project in 40 years, building one of the first combined heat and power plants made possible by a 1977 law change, and then helped TDEC prosper as its President.

This is a man who made a difference to so many people and left the world a better place.

Thank you Don for all you gave to us as we built an organization to profitably reduce greenhouse gas emissions.

I have cosindered Don as a good friend since the early 80's. He was always there for an invigorating intellectual discussion and a big smile. The deepest condolences from me and our family.

I have known Don since 1981. I consider him to be a friend, colleague and mentor. My condolences to the extended family.

I met Don at work in the early 80s...I'll never forget all the laughs I had with him and his secretary, Mary...My condolences to the Leibowitz family....

Don taught me how to (really) play chess, and to not hide my light under a bushel. During my early teens he was an important influence in my life and I have always been grateful for that. He filled a void as a role model during a difficult time and helped me recognize some things in myself that I cherish today. They say it takes a village to raise a child. I am grateful that Donald Leibowitz was in my village.
