Francis Amasa Walker was an American economist, statistician, journalist, educator, academic administrator, and an officer in the Union Army.

Sheffield Scientific School was founded in 1847 as a school of Yale College in New Haven, Connecticut, for instruction in science and engineering. Originally named the Yale Scientific School, it was renamed in 1861 in honor of Joseph E. Sheffield, a railroad executive. The school was incorporated in 1871. The Sheffield Scientific School helped establish the model for the transition of U.S. higher education from a classical model to one which incorporated both the sciences and the liberal arts. Following World War I, however, its curriculum gradually became completely integrated with Yale College. "The Sheff" ceased to function as a separate entity in 1956.
