David Swinson "Doc" Maynard (March 22, 1808 – March 13, 1873) was an American pioneer, doctor, and businessman. He was one of Seattle's primary founders. He was an effective civic booster and, compared to other white settlers, a relative advocate of Native American rights. His friendship with Chief Seattle was important in the formation of the city of Seattle, and it was he who proposed the city be named for this important chief.
