Dying to Do Letterman wiki

Letterman was born in Indianapolis,  His father, Harry Joseph Letterman (April 1915 – February 1973),[6] was a florist of English descent; his mother Dorothy Letterman (née Hofert, now Dorothy Mengering), a Presbyterian church secretary of German descent, is an occasional figure on the show, usually at holidays and birthdays.
Letterman lived on the north side of Indianapolis (Broad Ripple area), not far from Speedway, IN, and the Indianapolis Motor Speedway, and he enjoyed collecting model cars, including racers.[7] In 2000, he told an interviewer for Esquire that, while growing up, he admired his father's ability to tell jokes and be the life of the party. Harry Joseph Letterman survived a heart attack at age 36, when David was a young boy. The fear of losing his father was constantly with Letterman as he grew up.[8] The elder Letterman died of a second heart attack[9] at age 57.
Letterman attended his hometown's High School at the same time as Marilyn Tucker (future wife of Dan Quayle) and worked as a stock boy at the local Atlas supermarket.[10] According to the Ball State Daily News, he originally had wanted to attend Indiana University, but his grades were not good enough, so he decided to attend Ball State University, in Muncie, Indiana.[11] He is a member of the Sigma Chi Fraternity, and he graduated from what was then the Department of Radio and Television, in 1969. A self-described average student, Letterman endowed a scholarship for what he called "C students" at Ball State
