Legal name: Abel Meeropol
Abel Meeropol (February 14, 1903 – October 29, 1986) was an American writer, teacher and song-writer, whose works were published under his pseudonym Lewis Allan. His best-known song is "Strange Fruit" (1937), especially as recorded by Billie Holiday.
He and his wife Anne cared for and adopted Michael and Robert, the two young sons of Julius and Ethel Rosenberg, who were orphaned after their parents were executed for conspiracy to commit espionage -- the government accused them of having stolen the secret of the Atomic Bomb. The boys took the Meeropol surname to gain some privacy.
