From the moment Calvin Frye entered Mary Baker Eddy's employ in 1882 to the early December evening in 1910 when she passed on, he faithfully kept his original promise to her that he would stay with her. Calvin Frye's twenty-eight years of devoted personal service to our Leader is unmatched by any other Christian Scientist.
Mr. Frye's duties in "his many-sides post" Joseph G. Mann letter to William Lyman Johnson, January 24, 1919, Archives and Library of The Mother Church. (as a fellow worker called it) included serving as Mrs. Eddy's secretary, steward, confidant, metaphysical worker, coachman—or, as he himself put it in an interview, "her useful man." Quoted in The Denver Post, December 24, 1912.
To that end, he was always "on call." So much so that in 1910 when he and some others in the household took, with Mrs. Eddy's approval, a three-hour outing to see one of the first "aeroplane meets" held in the United States, it became, according to a cohort, "the longest vacation Mr. Frye had in all his years of service—certainly a mark of devotion." Irving C. Tomlinson reminiscences, p. 650, Archives. In 1906 Mr. Frye reckoned he had been away from Mrs. Eddy's residence "but four nights" since he first started working for her. Frye letter to Mrs. Eddy, August 17, 1906, Archives.
