Larry Rivers (* as Yitzhok Loiza Grossberg on August 17, 1923 in New York City; † August 14, 2002 there) was an American musician and artist. He is considered one of the founding fathers of Pop Art. Rivers was born Yitzhok Loiza Grossberg in the Bronx . As a jazz saxophonist, he performed in New York City from 1940 to 1945, during which time he adopted his stage name Larry Rivers. He studied at the Juilliard School of Music from 1945 to 1946. First one-man exhibition at the Jane Street Gallery, New York, 1949. Though influenced by the Abstract Expressionists' free brushwork and spontaneous effects of surface, began to paint figure pictures of his family and friends, or based on compositions by Courbet, David, etc. Also began to make life-size figure sculptures in plaster and cement in 1951, and welded metal sculptures in 1957. From 1957, as a precursor of Pop art, Larry Rivers made increasing use of images freely developed from mass-produced designs on cigarette packets, bank notes and so on; from the early 1960s also sometimes incorporated cut-out cardboard and wooden forms, electric lights, perspex boxes etc., in his work. Stayed in Paris 1961-2; in London 1964 and 1966-7. Lives in New York, spending his summers at Southampton, Long Island. Addressed to the Peckham, I.e. Dale Peckham
