Rev. Irving Clinton Tomlinson (March 22, 1860 – October 1, 1944) was an American Universalist minister who converted to Christian Science, becoming a practitioner and teacher. For a time, he lived as one of the workers in the household of church founder, Mary Baker Eddy, later writing a book about his experiences, called, Mary Baker Eddy: Twelve Years with Mary Baker Eddy.
Born Irving Clinton Tomlinson, in Perry, New York, he was the son of Dewitt Clinton, a minister and Emmeline C. Eaton Tomlinson. The family moved to Akron, Ohio, where his father was involved with raising funds to build a new Universalist educational institution, and where Tomlinson later went to preparatory school and college. He was the class president of a senior class of seven students, and business manager of The Argo, the first student publication at Buchtel College. He was also a member of Phi Delta Theta, a fraternity.
While a senior, he and his classmates decided to surpass an effort made by the previous year's graduating class, which had been to place a two-ton boulder on the campus, a lasting reminder of them. Tomlinson and his classmates searched the vicinity and located a syenite boulder on a farm belonging to the industrialist son of Akron's founder, Colonel Simon Perkins. Tomlinson was sent to purchase the "pebble", as they called it, which measured 7 feet tall, 5 feet wide and 3.5 feet across (2.1×1.5×1.1m) and 90 cubic feet (23 m3). The owner didn't want to sell and didn't think Tomlinson and his friends would be able to move it, saying "six yoke of oxen weren’t able to budge it." Tomlinson replied, “But, Colonel, that was a good while ago and things have changed. The telephone has been invented, and lots else, and I think we can get it.” They did have to pay a local building mover and the move took several days, but they were able to install "The Rock" on campus, where it remains a campus landmark.
Tomlinson graduated from Buchtel in 1880 with a B.A. and in 1883, with a M.A. Buchtel later became the municipal University of Akron. Tomlinson then enrolled in the theological program of Tufts College in Medford, Massachusetts, receiving a Bachelor of Divinity degree in 1888. Soon after graduating, he became the minister at the First Universalist Society of Arlington, Massachusetts, later First Universalist Church.
