Emslie John Horniman (1863 – 11 July 1932) was a British anthropologist, philanthropist and Liberal Party politician. The son of Frederick Horniman, sometime Liberal member of parliament for Penryn and Falmouth, Horniman was educated privately and at the Slade School of Fine Art. He spent his youth travelling widely, visiting Egypt, Morocco, Central Africa, India, Burma, the Dutch East Indies, French Indochina, China, Japan, and the United States. Like his father, the founder of the Horniman Museum, he was an enthusiastic collector of arts and "curiosities".
