Life
Coffin was born on September 6, 1806, in Williamsburg, Massachusetts. He was descended from Tristram Coffin, the first owner of Nantucket Island. Coffin was an orphan, and was raised by his uncle, the Reverend Moses Hallock. He attended Amherst College in Amherst, Massachusetts, from where he graduated in 1828. He had a son, Seldon J. Coffin. He died in 1873 on February 6.
Career
After graduating from Amherst, Coffin became a teacher at various schools and colleges. His career in meteorology began in 1838. He worked at Williams College in Williamstown, Massachusetts, from 1840 to 1843, during which he installed an apparatus for detecting the wind's direction and velocity, atop Mount Greylock, the highest point in Massachusetts. Together with William Ferrel, he deduced the Buys Ballot's law, which was named after the Dutch meteorologist C. H. D. Buys Ballot. He collaborated on meteorological studies with the Smithsonian Institution beginning in 1846. That same year, he acquired a chair at Lafayette College in Easton, Pennsylvania, in mathematics and natural philosophy, a position he held until his death.
