Charles P. Libby (1838-1895) was born in Portland, Maine, and died in Chicago, Illinois. He married Jennie S. Libby (b. Taylor) in Gorham, New Hampshire, in 1864. In 1869 he, along with his brother Arthur A. Libby and their partner Archibald McNeill, founded the Libby, McNeill & Libby Company, a canning plant that pioneered the process of canning beef and ultimately became one of the largest producers of canned foods in the world. It still operates in modern times. Charles Libby, who became president of the company, was one of the wealthiest and most prominent businessmen in Chicago during his lifetime. He was also director of the Atlas National Bank and a member of the Union League and Washington Park clubs. In 1886 Libby received Christian Science treatment from M. Bettie Bell, a student of Mary Baker Eddy's, and expressed interest in having his wife study with Eddy, although there is no record of her doing so.
