Adolph Friedrich Reinhardt (December 24, 1913 – August 30, 1967) was an abstract painter and Art theorist active in New York City for more than three decades.

Upon finishing college he was accredited as a painter by Burgoyne Diller, which allowed him to work from 1936 until 1940 for the WPA Federal Art Project, easel division.

Having completed his studies at the New York University Institute of Fine Arts, Reinhardt became a teacher at Brooklyn College in 1947 and taught there until his death from a heart attack in 1967.

Reinhardt's earliest exhibited paintings avoided representation, but show a steady progression away from objects and external reference.

[8] Reinhardt joined the staff of PM in 1942 and he worked full-time at this daily newspaper until 1947, with time out while drafted for active duty in the U.S. Navy.

Reinhardt also illustrated the highly influential and controversial pamphlet Races of Mankind (1943) originally intended for distribution to the U.S. Army, but after being banned subsequently sold close to a million copies.

While attending Columbia University he designed many covers and illustrations for the humor magazine Jester and was its editor in his senior year (1934–35).

Cartoons and illustrations were generally regarded as outside the canon of fine art in 1950s America, which was dominated by abstract painting.

In 2013, Robert Storr curated a dedicated room showcasing Reinhardt's cartoons at the David Zwirner Gallery in New York.
