Adrien-Marie Legendre (1752-1833) was a French mathematician who made numerous contributions to mathematics. Well-known and important concepts such as the Legendre polynomials and Legendre transformation are named after him.

Charles Davies (1798-1876) was a professor of mathematics at the United States Military Academy, notable for writing a series of mathematical textbooks. Davies joined the Light Artillery as a Bvt. Second Lieut. on December 11, 1815. He served a year in garrison at New England posts till August 31, 1816, when he was transferred to the Corps of Engineers. He resigned from the Army on December 1, 1816, and took a post as Assistant Professor of Mathematics at West Point (1823-1837).

From 1839 till 1841, Davies was a professor at Trinity College in Hartford, Connecticut, wherein he established a connection with Alfred Smith Barnes for publication of his books. He resigned from this position due to illness. He was reappointed in the army as a paymaster in November 1841, and was the Treasurer at West Point from December 11, 1841, to December 19, 1846. In 1848, he joined the New York University as a Professor of Mathematics and Natural Philosophy. Upon his retirement a year later, he was conferred the degree of Doctor of Law from Geneva College, New York. Davies had chosen to retire to devote more time in writing textbooks. After a brief teaching stint at the Normal School in Albany, New York, he accepted a position at Columbia College, New York City in 1857 and was appointed as emeritus professor in 1865.
