Clarke & Howe was an American architectural firm from Providence, Rhode Island that was active from 1893 to 1928. The firm was established in 1893 as Clarke & Spaulding, with Prescott O. Clarke and Arthur R. Spaulding. Wallis E. Howe was added as a partner in 1901, with the firm becoming Clarke, Spaulding & Howe. This association was short-lived, as Spaulding retired from architecture later that year. From 1907 to 1913 the firm was known as Clarke, Howe & Homer, with Eleazer B. Homer, a former MIT professor of architecture. Clarke & Howe was dissolved upon Clarke's retirement in 1928, with Howe continuing the practice as Howe & Church.
