Thomas Andrew Lehrer (; born April 9, 1928) is a retired American musician, singer-songwriter, satirist, and mathematician. He has lectured on mathematics and musical theater. He is best known for the pithy, humorous songs that he recorded in the 1950s and 1960s. His songs often parodied popular musical forms, though he usually created original melodies when doing so. A notable exception is "The Elements", where he set the names of the chemical elements to the tune of the "Major-General's Song" from Gilbert and Sullivan's Pirates of Penzance.

The sense of smell in the animal is what intuition is to the human spirit. It tells you of the invisible, of what cannot be detected by any other means. It tells you the things that are not there, yet are coming. You see into the blind, opaque past and round the corner of time.
