Sax Rohmer (pseudonym of Arthur Henry Ward; 1883–1959) was a British writer of songs sketches, plays and stories.
 Born in Birmingham to Irish immigrant parents, the family moved to London in about 1886, where Rohmer was schooled.
 His formal education finished in 1901, following the death of his alcoholic mother.
 After attempting careers in the civil service, as well as the banking, journalism and gas industries, Rohmer began writing comic songs, monologues and sketches for music hall performers, including Little Tich and George Robey.
 Rohmer's first book was "Pause!"
, a series of sketches conceived by Robey and written by Rohmer, which was published anonymously in 1910; his second book was the ghost-written biography of Little Tich, published with Tich's real name, Harry Relph.
