Nathaniel Lester Lanin (August 26, 1907 – October 27, 2004) was an American jazz and pop music bandleader.
Lanin's brothers, Sam and Howard, were also both bandleaders; they came from a family of ten (of which Lester was the youngest) born to a family of Russian Jewish immigrants. He originally attended South Philadelphia High School but quit at the age of 15 to play music with his brothers abandoning his plans to be an attorney. Beginning in 1927, he led ensembles that were paid to play at the houses of wealthy socialites in Philadelphia and New York, continuing after the 1929 stock market crash.
In 1930, Lanin was hired to play at a gala for Barbara Hutton, and the event garnered so much press in New York newspapers that it made Lanin a star as well as the young heiress. Lanin became a major star of the dance music world, and was hired worldwide to play for kings and queens, in addition to a recurring invitation to play at White House inaugural balls from the Eisenhower administration to the Carter administration. Lanin was managed for much of his career by New York socialite music promoter Al Madison.
