Biographical Note

Charles Frost was born in Lewiston, Maine, on May 31, 1856. He studied architecture for three years in several architects' offices and completed a special course in architecture at the Massachusetts Institute of Technology. Frost became a draftsman in Boston and worked for three years before moving to Chicago in 1882. There, he entered a partnership with Henry Ives Cobb, establishing the architectural firm Cobb & Frost (1882-1889). Afterward, Frost practiced alone for several years until becoming a partner in the firm of Frost & Granger. This practice was highly successful with railroad commissions. In 1911, following the breakup of the partnership, he maintained a private practice for the remainder of his working life. Charles Frost died in Chicago on December 11, 1931.
