Ezra Slocum Carr was a physician, educator, and professor. Born in Stephentown, New York, he was educated at Rensselaer Polytechnic Institute and graduated with an M.D. from Castletown College in Vermont in 1842.

He taught at several medical colleges in the East before coming to the University of Wisconsin (UW) in 1856 as professor of chemistry and natural history. He was a UW regent (1857-1859) and served as commissioner of the state geological survey. Active in political, agricultural, and medical affairs at the UW, Carr was recognized for his intellectual ability, but his tactlessness involved him in numerous controversies.

In 1867 Carr's contract was not renewed. He moved to California where he became a professor of agriculture at the University of California for six years. He was later California state superintendent of public instruction. He wrote extensively on agriculture and chemistry.
