Born in Milwaukee, he enrolled at the Carnegie Institute in Pittsburgh to study architecture but stayed only two years.

He was lighting supervisor for the WPA Theatre Project and production coordinator and lighting designer for American Ballet Theatre's first tour. His inventions include the reflector bulb, which he created with Clarence Birdseye, and the sealed beam reflector lamp.

With his company, Lighting by Feder, he was a lighting designer and/or consultant for the 1964 New York World's Fair, Expo '67, the San Francisco Civic Center, Rockefeller Plaza, the Israel National Museum in Jerusalem, and the Minskoff Theatre in New York, besides the lighting for all theatres in the Kennedy Center in Washington, DC.
