Brian Samuel Epstein ( ; 19 September 1934 – 27 August 1967) was an English music entrepreneur who managed the Beatles.  Epstein first discovered the Beatles in November 1961 during a lunchtime performance at The Cavern Club.  He was instantly impressed and saw great potential in the group.  Epstein was rejected by nearly all major recording companies in London, until he secured a meeting with George Martin, head of EMI's Parlophone label.  In May 1962, Martin agreed to sign the Beatles, partly because of Epstein's conviction that the group would become internationally famous.
