Lester Samuel Cohen, 84, a retired chemist, died March 22 at the Quadrangle in Haverford.

Cohen worked at the DuPont company for 25 years in Philadelphia and Delaware. He was once voted "Best Boss" at DuPont for his lifelong love of science and playful sense of humor.

Cohen was drafted out of college to serve in the Army as a medical laboratory technician during World War II. He was assigned to the U.S. Army Transport Excelsior, a troop ship, and participated in the D-Day invasion on June 6, 1944, at Omaha Beach in Normandy, France.

After the war, Cohen earned a bachelor's degree at the Philadelphia College of Pharmacy & Science, where he won a gold medal for graduating first in his class, and a master's degree and doctorate in chemistry at the University of Delaware.

As a reward for completing his education, he asked for a Toy Manchester Terrier, whom he named "Kemistree."

Cohen set up a laboratory with his brother Eugene, a D.Sc. chemist, before going to work at DuPont.

He was a founding president of Congregation Beth El Suburban, now Congregation Beth El-Ner Tamid, in Broomall, as well as a longtime member of the Marple Township Environmental Advisory Board.

He is survived by his wife, the former Selma Field, and daughters Celia Cohen and Bobbi Cohen. He was predeceased by his parents, Albert and Reba Cohen, and a brother, Eugene Cohen.
