Robert W. Patten

Robert W. Patten (1832–1913) was an American eccentric from Seattle, Washington. Few people in Seattle knew much about his past and he was seen as eccentric because of his lifestyle and outrageous claims. He lived on a houseboat, walked around town with an umbrella on his head, and spent most of his time outdoors. He claimed to have been a significant historical figure in his own right rating alongside Buffalo Bill and Kit Carson.

He did become a historical figure in a different way, as a recognized part of Seattle's cultural landscape, especially after cartoonist Dok Hager created a daily comic featuring his image. He was known as Old Sport or the Umbrella Man.
