John M. Tutt (March 20, 1879 – March 1, 1966) was an American medical doctor who converted to Christian Science in 1905, later becoming a practitioner in 1912, and then a teacher of Christian Science in 1916. One of his early patients was the mother of film actress Ginger Rogers.

Tutt was born in Missouri, the youngest of seven children. His father was a Baptist minister.^[1] Tutt received a B.A. degree from William Jewell College in Liberty, Missouri and in 1900, his medical degree from University Medical College of Kansas City when he was only 19.^[1][2]

In 1905, Tutt was healed in Christian Science of a stomach ailment, issues with his eyesight, smoking, drinking, and gambling which he compared to "the old story over again of the prodigal son and his awakening."^[3] He took a Christian Science primary class from Adam H. Dickey in 1912.^[4] He has been called the best known convert to Christian Science to come from medicine.^[5] Tutt became a practitioner in 1912 and a teacher of Christian Science in 1916. From 1915 to 1918, he was the Committee on Publication for the state of Missouri.^{[1][note 1]}

One of Tutt's early cases as a practitioner was that of a kidnapped toddler in Kansas City.^[7][8] The little girl, Virginia McMath, later became known as Ginger Rogers, a Hollywood actress. Tutt became a Christian Science lecturer in 1918, continuing for the next 30 years. He taught the 1943 Normal class in the Christian Science Board of Education,^[9] which trains new teachers of Christian Science. The class is held just once every three years and is limited to 30 students. The 1940 United States Census records him as having worked 52 weeks during the previous year.^[10] He continued teaching primary classes through 1965.^[4]

Tutt and his wife Alice had a son, Robert T. Tutt.^[10]
