Leo Hellerman Obituary
Dutchess County - Leo Hellerman died this past February 1 at Northern Dutchess Hospital after a brief illness. He was a graduate of Yale University with a doctorate in mathematics. He held many positions in his work with IBM. In addition to his involvement with microprogramming, he authored several articles as president of the Scientific Research Society of America.
After retirement from IBM, Dr. Hellerman met and married his second wife, Dorothy. Together, they enjoyed hiking, camping, and travel, both in the US and abroad. Trained in music and piano, Leo gave great pleasure to friends and family with his musical talents.
Leo is survived by his wife Dorothy, three children from his first marriage to Marcia Hellerman: sons David and Daniel, and daughter Lisa Kopchik, as well as four grandchildren: Francesca, Aaron, David, and Siri.
Dr. Hellerman had a lively intelligence, always questioning himself and others about concerns and happenings of life. Loved and respected by all who knew him as a talented, wise, and gentle man, he will be greatly missed.
There will be a memorial service for Leo at 2 pm Saturday, April 13 at the Unitarian Universalist Congregation of the Catskills, 320 Sawkill Road, Kingston, NY.

I met Leo many years ago when we both worked for IBM in Böblingen Germany. We soon became close friends spending much time together, hiking, talking about mathematics and philosophy, When Leo returned to the US and I moved to Switzerland our contact relied mostly on email. When my wife and I visited New York we also met Leo and went hiking with him in the Catskill mountain. This was the last time we met. After that time our contact dwindled over the years, and I learned only recently that he passed away in 2019.
