William Williams Chapman was a nineteenth-century American lawyer, politician, and civic promoter who played a significant role in the early development of both Iowa and Oregon. Born and raised in Virginia, Chapman began his career in law and public service in the Midwest. He served as a United States Attorney in Iowa during its period as part of the Michigan and Wisconsin territories, and later represented the Iowa Territory in the United States House of Representatives.\n\nAfter his tenure in Iowa, Chapman immigrated westward to the Oregon Country, where he continued his political career. He served in the Oregon Territorial Legislature and later in the Oregon Legislative Assembly. Settling in Portland, Chapman became a prominent civic figure, promoting the city's economic interests, advocating for the expansion of railroads, and helping to construct Canyon Road.\n\nIn addition to his political and infrastructure endeavors, Chapman was a co-founder of The Oregonian newspaper, which grew to become a major regional publication. He was also active in local military affairs, fighting in the Rogue River War. His enduring legacy in Portland is preserved in Chapman Square, a prominent downtown park established on land he sold to the city.
