The son of Russian immigrants, Wiener was a child prodigy, obtaining his PhD (in mathematical logic) from Harvard U at the age of eighteen. He developed the mathematics of a Wiener process, the simplest type of Brownian motion. His interests were wide-ranging: he became well known to the general scientific public for his philosophical discussion of cybernetics (a term he coined in 1945). Amongst his sayings is ‘A professor is one who can speak on any subject—for precisely fifty minutes’, though some might disagree with this observation! A lunar crater is named after him.
