Reuben Epstein, 78, passed away peacefully on March 2nd, 2026, surrounded by his family.

His love of music also started young. Reuben took up playing the violin as a child and continued with the University of Rochester Symphony Orchestra, as well as with chamber music groups, throughout his career

Reuben was endlessly curious and passionate about science, music, poetry, and puns, but he loved his family most of all.

Reuben is survived by his loving wife of 52 years, Jody Siegle; children, Aaron (Rebecca) Epstein, Eric Epstein, and Chloe Epstein; grandchildren, Samuel Epstein and Andrew Epstein; and brother, Albert Epstein.
