Ad Reinhardt
Adolph Frederick Reinhardt ("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 founding member of the Artist's Club. 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. He believed in a philosophy of art he called Art-as-Art and used his writing and satirical cartoons to advocate for abstract art and against what he described as "the disreputable practices of artists-as-artists".
