Irving Paul "Swifty" Lazar (March 28, 1907 – December 30, 1993) was an American talent agent and dealmaker, representing both movie stars and authors.
Born Samuel Lazar in Brooklyn, New York, he graduated from Brooklyn Law School in 1931. While practicing bankruptcy law during the early 1930s, he negotiated a business deal for a vaudeville performer Ted Lewis, and realized the income potential for acting as an agent.
Lazar moved to Hollywood in 1936 but maintained a presence in New York until after World War II when he moved to Los Angeles permanently. After putting together three major deals for Humphrey Bogart in a single day, he was dubbed "Swifty" by Bogart, a nickname he actually disliked.
In addition to Bogart, Lazar became the agent representing the top tier of celebrities, including Lauren Bacall, Truman Capote, Cher, Joan Collins, Noël Coward, Ira Gershwin, Cary Grant, Moss Hart, Ernest Hemingway, Gene Kelly, Madonna, Walter Matthau, Larry McMurtry, Vladimir Nabokov, Clifford Odets, Cole Porter, William Saroyan, Irwin Shaw, President Richard Nixon and Tennessee Williams. Lazar's power became such that he could negotiate a deal for someone who was not even his client and then collect a fee from that person's agent.
