Religion was less of a force in Seattle than in eastern cities, but the Protestant Social Gospel movement had a national leader in the Rev. Mark A. Matthews (1867-1940) of Seattle's First Presbyterian Church. He was a tireless reformer who investigated red light districts and crime scenes, denouncing corrupt politicians, businessmen and saloon keepers. With 10,000 members, his was the largest Presbyterian Church in the country, and he was selected the denomination's national moderator in 1912. He built a model church, with night schools, unemployment bureaus, a kindergarten, Anti-tuberculosis clinics, and America's first church-owned radio station. Matthews was the most influential clergymen in the Pacific Northwest.
