Tom Lehrer was an American mathematician, satirist, songwriter, and pianist, born on April 9, 1928, in Manhattan, New York City. He entered Harvard University at age 15, earning a Bachelor of Arts in mathematics in 1946 and a Master of Arts in 1947. Lehrer remained at Harvard as a graduate student until 1953, but never completed a doctorate, and preferred to be addressed as "Mr. Lehrer." Lehrer began writing and performing satirical songs in the early 1950s, initially to amuse friends. His first album, "Songs by Tom Lehrer," was released in 1953 and sold from his home by mail, eventually becoming an underground hit. He gained wider recognition with subsequent albums, including "More of Tom Lehrer" (1959) and the live recording "An Evening Wasted with Tom Lehrer," which was nominated for a Grammy in 1960. His songs, known for their wit, wordplay, and sharp social commentary, lampooned topics such as politics, science, and social conventions. Notable songs include "Poisoning Pigeons in the Park," "The Old Dope Peddler," "The Vatican Rag," and "The Elements," which set the names of chemical elements to music. Lehrer served in the U.S. Army from 1955 to 1957. In the 1960s, he wrote songs for the satirical television show "That Was The Week That Was." He largely retired from public performances in the 1970s, returning to teaching mathematics, notably at the University of California, Santa Cruz, until his retirement. Lehrer's work remains influential for its clever lyrics and satirical edge. He died on July 26, 2025, in Cambridge, Massachusetts, at the age of 97.
