Martin Greenfield, born in a part of Czechoslovakia that is now Ukraine and who was sent to Auschwitz as a teenager and later became a tailor for clients, including six U.S. presidents and numerous celebrities, died on March 18 at his home in Brooklyn. He was 95.

Beaten in the camp for ripping a shirt, a fellow prisoner taught him to sew. At age 19, he was freed, and he boarded a ship to New York with $10 in his pocket. Mr. Greenfield became arguably the best men’s tailor in the United States.
