Early life

His mother was the niece of Rufus King, U.S. minister to Great Britain.[1] He graduated Bowdoin College in 1834 with a Bachelor of Arts.[2][3] In 1834, Coffin went on a sea voyage with his uncle Captain King Porter and learned navigation and seamanship.[1][4] He graduated with a Master of Arts from Bowdoin College in 1837.[3] His sister married William Smyth, professor at Bowdoin College.[5]
Career
editIn 1836, Coffin became a professor of mathematics with the United States Navy. He taught midshipmen at sea and on land at the Norfolk Navy Yard.[4] During this time, Coffin also served on the USS Vandalia, the USS Constellation and on surveys in Florida.[2] Coffin was retained as a senior professor in 1848 when the corps was reduced.[6]
Coffin was stationed at the United States Naval Observatory in Washington, D.C., starting in January 1845. He was in charge of the mural circle and remained there until 1853, after suffering an eye disease.[1][4][6]
In 1853, Coffin became the head of the mathematics department at the United States Naval Academy. In 1860, Coffin also became head of the navigation and astronomy department, replacing the retiring William Chauvenet. Following the outbreak of the Civil War, the Naval Academy moved to Newport, Rhode Island, and Coffin was the head of all departments during that period.[1][2] His textbook "Navigation and Nautical Almanac" was used for over thirty years in instruction at the Naval Academy.[1]
Coffin served as the superintendent of the American Ephemeris and Nautical Almanac starting on May 1, 1866. In 1867, he moved from Cambridge, Massachusetts, to Washington, D.C., when the almanac moved its place of publication. He retired on September 15, 1877.[1][2][4]
Coffin was elected as a member of the American Academy of Arts and Sciences in 1851. He became an associate fellow.[2][7] He was also a member of the American Philosophical Society. In 1863, Coffin was appointed as one of the first members of the National Academy of Sciences by the U.S. Congress.[2][8]
