William Stern (psychologist)
William Stern (29 April 1871 - 27 March 1938), born Louis William Stern, was a German psychologist and philosopher noted as a pioneer in the field of the psychology of personality and intelligence. He was the inventor of the concept of the intelligence quotient, or IQ, later used by Lewis Terman and other researchers in the development of the first IQ tests, based on the work of Alfred Binet. He was the father of the German writer and philosopher Günther Anders. In 1897, Stern invented the tone variator, allowing him to research human perception of sound in an unprecedented way.

Famous quotes containing the word stern:
“We tried pathetic appeals to the wandering waiters, who told us “they are coming, Sir” in a soothing tone—and we tried stern remonstrance, & they then said “they are coming, Sir” in a more injured tone; & after all such appeals they retired into their dens, and hid themselves behind sideboards and dish-covers, still the chops came not. We agreed that of all virtues a waiter can display, that of a retiring disposition is quite the least desirable.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
