David Thomas Denny (March 17, 1832[1] – November 25, 1903[2]) was a member of the Denny Party, who are generally collectively credited as the founders of Seattle, Washington, United States. Though he ultimately underwent bankruptcy, he was a significant contributor to the shape of the city.[2] Roger Sale, in his book Seattle, Past to Present, described him as having been "the pioneer to turn to if one had a plan that would be 'good for Seattle', and one needed a respectable tone and a willing investor."[3]
