John H. Reed, a potato farming boy who became Maine governor by surprise and then went on to serve an ambassadorship, is perhaps the best-known Mainer or person with close ties to the state who died during 2012.

The list includes other politicians, educators, business leaders and Mainers who achieved fame in unique ways. Frank Knight was longtime protector of New England’s tallest elm tree, actress Phyllis Thaxter was seen by millions playing her “Superman” movie role, and Bryce Bayer invented a part used in nearly every digital camera.

Reed, 91, died Oct. 31 in Washington, D.C., after an illustrious life in politics.

A Fort Fairfield native, Reed grew up in a potato farming family and served in the Navy during World War II and in the Maine Legislature from 1955 to 1959. While he was state Senate president, Reed became governor in September 1959 upon the unexpected death of Gov. Clinton Clauson. Reed was appointed in 1967 to the National Transportation Safety Board and was U.S. ambassador to Sri Lanka and Maldives in 1976-77.
