Born in Riga (now Latvia) Russia, Yunkers traveled extensively trough Germany, France, Spain, Sweden, and Cuba early in his career. Relocating to New York in 1947, Yunkers quickly became active with the nascent Abstract Expressionist group.

Yunkers was also an active bookmaker and printmaker, founding the Rio Grande Workshop in New Mexico.
