Sir John Martin-Harvey (22 June 1863 – 14 May 1944), known before his knighthood in 1921 as John Martin Harvey, was an English stage actor-manager. Born in Bath Street, Wivenhoe, Essex, he was the son of John Harvey, a yacht-designer and shipbuilder, and Margaret Diana Mary (née Goyder). His father expected him to follow his own profession, but Martin Harvey had his sights set on the stage. One of his father's clients was the dramatist W.S. Gilbert, and it was through Gilbert that young Martin Harvey met his first teacher, John Ryder.
