Emmet Densmore (May 19, 1837 – March 2, 1911) was an American businessman, physician and natural hygiene advocate who promoted an early version of the Paleolithic diet.

[1] He bought and sold oil wells and for several years worked with his brother James Densmore in developing the Sholes typewriter.

[6] He was President of the Barnard Densmore Company which manufactured distilled water and preserved fruits in Los Angeles.

It does not matter what title we give the Supreme Ruler: Natural Law, or God, or what you will: there seems to me conclusive evidence of intelligent design in the Great Artificer.

"[8] Densmore promoted a fruit and meat diet, which he believed was the natural food of primal man.

[13] His recommended diet consisted of fruit, meat, nuts, fish, eggs and milk.

[11] He opposed the use of all drugs and believed that dietetic and natural hygienic measures could cure disease.

[19][20] In 1890, Densmore and Helen founded the Natural Food Society in London which offered a system of dietary principles that was more enjoyable and practical than "orthodox vegetarianism or the ordinary fare".

Obituaries in several medical journals and newspapers have stated that Densmore died at Cassadaga, Florida after two years of illness on February 18, 1911.
