John and Vera Richter

Dr. John Theophilus Richter (June 10, 1863 – January 24, 1949) and Vera M. Richter (December 11, 1884 – January 13, 1960) were an American married couple who ran an early health food restaurant in Los Angeles, the Eutropheon, which became a meeting place for influential figures in the development of alternative lifestyles in California between 1917 and the late 1940s.

Theophilus John Richter was born in Illinois, the first son of Pastor Frederick Leberecht Richter and his wife Caroline Wilhelmina (née Grauman), who were immigrants from Germany and married in Chicago. When he was a child, the family lived in St. Peter, Minnesota, and Minneapolis, before settling in the late 1870s in the newly established city of Fargo, North Dakota, where Pastor Richter became a drug store owner and physician. During the 1880s, Theophilus Richter worked as a machinist while taking a natural healing course in Chicago, based on the "Battle Creek" system devised by John Harvey Kellogg. He adopted a vegetarian diet, and also gained a diploma in the “Swedish movement cure”. According to Richter, he took over some of his father's patients in Fargo, and began treating them successfully using natural remedies. In 1891 he married Violet Berry, and in the early 1900s they moved with their children from Fargo to Minneapolis. He gained a qualification and began practicing there as a naturopathic physician. By 1911, he adopted a raw food diet, influenced by the theories of Benedict Lust and talks held in Minneapolis by a Chicago doctor, George Drews, and decided to dedicate his life to the promotion of the raw vegetarian diet.
