Donald Baxter MacMillan was an American explorer, sailor, researcher and lecturer who made over 30 expeditions to the Arctic during his 46-year career.

Bowdoin is a historic schooner built in 1921 in East Boothbay, Maine, at the Hodgdon Brothers Shipyard. Designed by William H. Hand, Jr. under the direction of explorer Donald B. MacMillan, the gaff-rigged vessel is the only American schooner built specifically for Arctic exploration. She has made 29 trips above the Arctic Circle in her life, three since she was acquired by the Maine Maritime Academy as a sail training ship in 1988. She is currently owned by the Academy, located in Castine, Maine, and is named for Bowdoin College.
