William Chauvenet (24 May 1820 in Milford, Pennsylvania – 13 December 1870 in St. Paul, Minnesota) was a professor of mathematics, astronomy, navigation, and surveying who was instrumental in the establishment of the U.S. Naval Academy at Annapolis, Maryland, and later the second chancellor of Washington University in St. Louis. Early life William Chauvenet was born on a farm near Milford, Pennsylvania to Guillaume Marc Chauvenet, a former soldier of Napoleon's army reconverted in silk trade after the Emperor's fall, and Mary B. Kerr and was raised in Philadelphia. He entered Yale University at age 16, and graduated in 1840 with high honors. While at Yale, Chauvenet contributed to the school newspaper and was a pianist with the Beethoven Society. He was one of eight founding members of the Skull and Bones Society. United States Navy In 1841, he was appointed a professor of mathematics in the United States Navy, and for a while served on the USS Mississippi teaching math. His professorship led Chauvenet to see the necessity of a United States naval academy. While others had proposed the idea, no one had actually seen it through. In 1842, he was appointed head of the naval asylum in Philadelphia, Pennsylvania. At the Naval Asylum, prospective officers took an eight-month course before sailing. Chauvenet felt the course was lacking and drew up his own plan for a two-year course. Presenting to several secretaries of the navy, the course was finally accepted in 1845. He was instrumental in the 1845 founding of the United States Naval Academy at Annapolis, Maryland, and taught there for years. He was president of the academic board and in 1851 was part of a board that recommended the course of study be extended to four years. Chauvenet taught in many subjects, including mathematics, surveying, astronomy, and navigation. He helped to establish an astronomical observatory at the naval academy. Chauvenet's contributions were so important that in 1890, Admiral S.R. Franklin proclaimed him "Father of the Naval Academy". A bronze plaque was installed with this inscription in 1916, at the behest of Congress. In 1855, he declined Yale's offer of a professorship of mathematics to continue working at the Naval Academy in Annapolis. Washington University In 1859, Yale again came calling, offering this time the professorship of astronomy and natural philosophy. Instead, Chauvenet took a job offered by Washington University in St. Louis: professor of mathematics and astronomy.
