Donald Baxter MacMillan (November 10, 1874 – September 7, 1970) was an American explorer, sailor, researcher and lecturer who made over 30 expeditions to the Arctic during his 46-year career. He pioneered the use of radios, airplanes, and electricity in the Arctic and put together a dictionary of the Inuktitut language. His expeditions produced Inuit films, photographs of Arctic scenes, and audio recordings of Inuit languages, thousands of which were taken by Miriam MacMillan. In 1921, he designed the Bowdoin schooner (named for Bowdoin College), which sailed to the Arctic two dozen times. Early life Born in Provincetown, Massachusetts in 1874, MacMillan lived in Freeport, Maine after the deaths of both his parents in 1883 (his father died while captaining a Grand Banks fishing schooner) and 1886 (his mother died suddenly), and was educated at Bowdoin College in Brunswick, graduating in 1898 with a degree in geology. He later taught at Worcester Academy from 1903 to 1908. Personal life Donald MacMillan would often visit his close friends Jerome and Amy Look between Arctic expeditions. Each time, he would bring gifts for their daughter, sailor Miriam Norton Look; "a beaded craft, an ivory figurine, or some other token of his adventures in the North." Look referred to MacMillan as "Uncle Dan," and they would correspond via letters. While piloting her Sea Pup motorboat, Look recognized Donald MacMillan's 88-foot Bowdoin schooner, which had dropped anchor near Bustins Island. Look piloted her boat to MacMillan, who ran summer camps for boys on the island, and asked if he needed a ride. MacMillan accepted her offer, as he stated he had a dinner date that evening. However, the boat ran out of gas minutes later, and MacMillan was a half-hour late to his dinner date. Nevertheless, he stated he was impressed with Look's "expert control" of the motorboat. On March 18, 1935, when he was 61 years old, MacMillan married sailor, author, and photographer Miriam Norton Look, then 29 years old. In 1937, Miriam MacMillan said she would like to accompany MacMillan to the Inuit town of Nunainguk, Newfoundland and Labrador. He agreed on the stipulation that she would arrive in nearby Hopedale without his assistance. Deciding it would be a race, MacMillan reached Hopedale days before her husband did, traveling by train and mail carrier. Before his arrival, she studied Inuktitut, custom-made Inuit clothing, and asked locals to tell her stories about Donald.
