Calvin Augustine Frye (August 24, 1845 – April 26, 1917) was the personal assistant of Mary Baker Eddy (1821–1910), the founder of Christian Science. Living in Eddy's homes at 569 Columbus Avenue, Boston, and later at Pleasant View, Concord, New Hampshire, and Chestnut Hill, Massachusetts, Frye ran the houses, managed her personal affairs, and dealt with her official correspondence. He was reportedly with her practically every day from August 1882, when he joined her household as her chief aide, until she died in December 1910.
Frye became known locally during his lifetime for taking Eddy for a daily ride in a horse-drawn carriage, with Frye dressed in a uniform and top hat sitting next to the coachman. He is known within Christian Science historiography chiefly for the diary he left behind, which details Eddy's domestic life. Caroline Fraser wrote in 1999 that the diary, and notebooks Frye kept of Eddy's dictation, are "among the most mysterious and coveted documents held by the [Christian Science] church," and that, at the time of writing, no outside scholars had been allowed to see the originals.
Excerpts from the diary appeared in Ernest Sutherland Bates and John V. Dittemore's Mary Baker Eddy: The Truth and the Tradition (1932). Dittemore had been on the board of directors of the Christian Science church, though became estranged from them. Frye had removed parts of the diary that were the most incriminating and had entrusted them to the church; Dittemore copied them, burned the originals, and years later published them.
Frye is buried in the West Parish Garden Cemetery in Andover, Essex County, Massachusetts ( in Plot 02-123f ).
