Adolph Frederick “Ad” Reinhardt (December 24, 1913 – August 30, 1967) was an abstract painter active in New York beginning in the 1930s and continuing through the 1960s. He was a member of the American Abstract Artists and was a part of the movement centered on the Betty Parsons Gallery that became known as abstract expressionism. He was also a member of The club, the meeting place for the New York School abstract expressionist artists during the 1940s and 1950s. He wrote and lectured extensively on art and was a major influence on conceptual art, minimal art and monochrome painting. Most famous for his “black” or “ultimate” paintings, he claimed to be painting the “last paintings” that anyone can paint.
