Webber was born in Byfield, Massachusetts, in 1759.1 He was educated at Dummer Academy (now known as The Governor's Academy) and Harvard College (B.A., 1784; M.A., 1787) where he distinguished himself in mathematics. He was a member of the Hasty Pudding. Webber was ordained as Congregational minister in 1787 and two years later became Hollis Professor of Mathematick and Natural Philosophy at Harvard.2 He served in the commission that drew the boundaries, later recognized by the Treaty of Paris, between the new United States of America and the surrounding British provinces. He was elected a Fellow of the American Academy of Arts and Sciences in 17893 and also served as vice-president of the Academy. He authored System of Mathematics, which for many years served as the only textbook on the subject in New England.4
Webber was appointed president of Harvard in 1806. That same year he received an honorary Doctor of Divinity degree from that institution. He led Harvard until his death in Cambridge, Massachusetts on July 17, 1810.5
Webber's son, Samuel Jr., married Anna Winslow Green, a granddaughter of David Mathews, Loyalist Mayor of New York City under the British during the American Revolution. Webber's son, also named Samuel (September 15, 1797 Cambridge, Massachusetts – December 5, 1880 Charlestown, New Hampshire), was a distinguished physician, chemist and author.6
