Timothy F. Callahan (March 1, 1856 – October 22, 1934) was an American politician and businessperson from Maine. Callahan, a Democrat from Lewiston, served one term in the Maine House of Representatives (1891–1892).[1] He also was elected by the Maine Legislature to serve as the third Maine State Auditor (1913–1915).[2]
Callahan's parents, John and Margaret Callahan,[3] were both Irish immigrants. He and his brother Eugene Callahan were merchants. The brothers erected two Renaissance-style commercial buildings in downtown Lewiston; the first in 1892 and the second in 1910–11. They sold trunks, hats and men's clothing.[4]
