Tom Lehrer, American singer, comedian and mathematician (born 1928)

Thomas Andrew Lehrer was an American musician, singer-songwriter, satirist and mathematician, who later taught mathematics and musical theater. He recorded pithy, humorous, and often political songs that became popular in the 1950s and 1960s. His songs often parodied popular musical forms, though they usually had original melodies. An exception is "The Elements", in which he set the names of the chemical elements to the tune of the "Major-General's Song" from Gilbert and Sullivan's The Pirates of Penzance.
