He was the son of Edward Whitehouse and Julia Eliza Cammann. He married May Schenck, by whom he had five children.
He started working at the firm of Cammann and Whitehouse, stockbrokers, in Wall Street, at a young age. He became one of the partners in 1855 when the firm was reorganized under the title of Whitehouse, Son and Morrison. In later years the firm was renamed Whitehouse and Company.
