Bio
Arthur Armstrong Denny (1822-1899) was an American politician, businessman, and one of the founders of Seattle, Washington. Born in Indiana, Denny’s early life in Illinois was marked by hardship, where he balanced school with caring for his ailing mother. He studied carpentry, surveying, and civil engineering, becoming a county surveyor in 1843. After marrying Mary Ann Boren, the couple had six children.
In 1851, Denny led the Denny Party west, arriving at Alki Point in Puget Sound before relocating to what is now Seattle. He quickly became involved in business and politics, helping establish the Washington Territory in 1853. Over his career, Denny held several public offices, including Seattle’s first postmaster and a member of the territorial legislature for nine consecutive terms. He also played a key role in founding the University of Washington, donating land for its original site.
As a businessman, Denny partnered with Dexter Horton in founding Seattle’s first bank, which eventually became Seattle-First National Bank. He was also president of the Seattle and Walla Walla Railroad Company. Later in life, Denny authored a memoir, Pioneer Days in Puget Sound, recounting his experiences. He was a conservative Christian, lifelong teetotaler, and an advocate for women’s suffrage, introducing a bill for women’s voting rights in 1854, though it was unsuccessful.
Denny’s legacy endures through various landmarks in Seattle, including Denny Hall at the University of Washington.
