Jas. P. (James Piper) Cadman (1842-1932) was born in Adrian, Michigan, and died in Los Angeles, California. He graduated from Kalamazoo College in 1863 and enlisted in the Union Army, serving in the Michigan 11th and 8th Volunteer Cavalry Regiments during the Civil War. After the war, he held many different jobs, including editor of the Michigan Christian Herald (1866-1868), sewing machine salesman (1875-1878), and secretary of the American Publishing Society of Hebrew (1885-1890). Cadman also authored the book, Critical Harmony of the Gospels (1885). He was healed by Bradford Sherman, a student of Mary Baker Eddy's, and although Cadman expressed an interest in Christian Science, there is no record of him studying with Eddy or uniting with the Church of Christ (Scientist).
