Raymond Seltzer
Raymond Seltzer, of West Nyack, NY, passed away peacefully on March 26, 2026, at the age of 90. A devoted and loving husband, father, grandfather, brother and friend, he will be deeply missed.
Ray was born in 1935 in the depression-era Bronx, NY. Like many from his neighborhood of that generation, he grew up with very modest means, but plenty of grit. From an early age, his parents Yetta and Louis instilled in him a deep respect for education and he excelled in the classroom. Outside of school, he loved spending time with older brother Norman and cousins Cissy Sands, Ida Friedman, and Jack Ossofsky. He developed a deep love of sports, playing stickball and kick the can, and a fondness for egg creams and malteds at the soda shop.
He attended The City College of New York, graduating with a B.S. in 1956, and then earned a Ph.D. in Chemistry from Purdue University in 1961. He fondly recalled his graduate school days, often sharing stories of applying his chemistry knowledge to extracurricular pursuits, such as distilling gin in his apartment bathtub.
In 1964, Ray met his wife Sylvia at a charity event, a fitting beginning for a life defined by generosity and care for others. They married in 1966 and built a beautiful life together through 60 years of marriage, from the early days in Manhattan to raising a family in New City and then in their retirement years in West Nyack. They enjoyed traveling, theater, restaurants, museums, and opening their home to family and friends.
There’s nothing Ray loved more than entertaining. He was in his element on his deck in the summer, tending the grill and celebrating birthdays, graduations, or just hosting family and friends. But as much as he loved a party, he never wanted to be the center of attention. Whenever others celebrated him, he quickly pivoted to planning something special for his wife, including a surprise 40th birthday and a retirement celebration.
Ray’s selflessness and devotion to family was core to his being. When his wife was diagnosed with Multiple Sclerosis, he made sure they continued to enjoy the life they loved. Everywhere they went, he was a one-man advance team, scouting out every location in advance to ensure it was accessible and that she would be comfortable. They were true partners in every sense.
Ray was a distinguished chemist and inventor. After early roles at Kodak and M&T Chemicals, he joined Ciba-Geigy in 1968, where he spent 35-years, and rose to become Vice President and Head of U.S. Research. His contributions to his field are reflected in the binders filled with his patents and publications, and the multiple research awards that lined his office wall, including the prestigious R&D 100 award, received in 1990.
While he loved his job, he also had a deep passion for teaching. He taught chemistry at Pace University for over 40 years, first at night and later during the day after retiring. He taught until he was 88, even throughout the pandemic, learning how to use a special tablet to write equations and formulas to his students online.
Despite his success, Ray remained grounded in the values of his upbringing. He instilled a strong work ethic in his children and carried a deep sense of substance over style. He discouraged chasing trends—especially when it came to material things like clothes or cars. His children recall his dislike for brand-name labels when they were growing up. He’d say, “I’m not buying you a shirt just to advertise a company’s name. They should pay you to wear that!”.
As a father, Ray was caring, thoughtful, funny, serious, and encouraging. He relentlessly supported his children, be it coaching a team, helping with homework, offering advice, or just checking in. He ensured they had the opportunities he hadn’t: music lessons, skiing, hiking, summer camp, theater and travel.
Ray delighted in having new members of the family to love and support, spending time with his daughter-in-law on visits to Seattle and talking to his son-in-law about his business. And he was never more thrilled than when his family grew to include his four grandchildren. He treasured every moment with them, diving into their latest interests, and of course, always helping with chemistry homework.
Ray is survived by his wife Sylvia, his children Gabrielle (Verkman) and Michael, and his four grandchildren Jacob, Nathan (Verkman), Talia, and Sydney (Verkman).
Donations in his memory can be made to the American Stroke Association, the National Multiple Sclerosis (MS) Society, Save the Children, and the Sierra Club.
