David Leibnitz Obituary

Obituary published on Legacy.com by Joseph J Smith Funeral Home Inc on Dec. 22, 2025.
David P. Leibnitz, of Patterson, NY, passed away unexpectedly on December 19, 2025, at the age of 67. He was born on September 1,1958 in Brooklyn, NY, son of Eugene and Roslyn Leibnitz.
David attended the University of Pennsylvania and earned a Bachelor's Degree in Chemical Engineering. He loved antique cars and enjoyed working on his 1964 Ford Galaxie and Datsun 240 Z. He also liked to tinker and repair antique clocks. The challenge of the intricate precision required was a testament to his intellectual, active mind. David was also an avid animal lover; his furry companions miss him already.
Dave is survived his wife Mary, his mother Roslyn, his daughters Jennifer and Victoria, and his siblings Edward Leibnitz and Laura Lerner. He was predeceased by his father Eugene.
All are welcome to attend a memorial visitation on Saturday, January 3rd from 11AM-1PM at the Joseph J. Smith Funeral Home in Mahopac, NY. A private cremation was held prior to services.
In lieu of flowers, please make memorial contributions in his name to the American Heart Association, www.heart.org.
