BiographyDuring Seattle's early history, Arthur Armstrong Denny was its wealthiest citizen, who owned vast property, both real estate and personal, the latter covered banking, street railway, irrigation, and other properties. He was born on June 20, 1822 near Salem, Washington County, Indiana to John and Sarah (Wilson) Denny. Denny's family subsequently settled in Knox County, Illinois where Arthur attended school. He became a civil engineer and in 1843 elected county surveyor of Know County, Illinois. Also in 1843, Arthur married Mary Ann Boren with whom he had six children: Louisa Catherine Frye, Margaret Leona Denny, Rolland Herschell Denny, Orion Orvil Denny, Arthur Wilson Denny, and Charles Latimer Denny.

Arthur Denny sold cargo on commission for ship captains until 1854 when he began a partnership with David Phillips and Dexter Horton in general merchandise.
