Robert William Lamm (born October 13, 1944) is an American keyboardist, singer and songwriter best known for being a founding member of the rock band Chicago. He wrote many of the band's biggest hits, including "Does Anybody Really Know What Time It Is?," "Beginnings," "Saturday in the Park," and "25 or 6 to 4."
Robert Lamm was born in Brooklyn, New York and raised in Chicago, Illinois.
He studied art in high school, particularly drawing and painting, but changed direction in college by enrolling in the music program at Roosevelt University in Chicago. In a 2003 interview, Lamm said, "My early training was really as a member of a church choir when I was a kid. It was a very good choir in Brooklyn, New York (Harry Chapin and members of his band were also in this choir at around the same time). It exposed me to some of the great sacred music from the Middle Ages, right up through Bach and into some of the 20th Century composers."
