Calvert DeForest  Calvert Grant DeForest (July 23, 1921 – March 19, 2007), also known by his character Larry "Bud" Melman, was an American actor and comedian, best known for his appearances on "Late Night with David Letterman" and the "Late Show with David Letterman". Little has been published about his early life. He was born to Calvert Martin DeForest, M.D., a physician who died in 1949, and Mabelle (Taylor) DeForest. Calvert's father was a cousin of radio pioneer Lee de Forest. DeForest attended Poly Prep Country Day School in Brooklyn, New York. He was employed for many years as a file clerk at the pharmaceutical company Parke-Davis, which was later acquired by Pfizer. He had aspirations of acting but was discouraged by his mother, who was briefly an actress herself. After her death in 1969, DeForest did part-time backstage work, which eventually led to acting work, and is credited with appearing in five films from 1972-82. He worked part-time as a receptionist at a drug rehabilitation center until February 1984, when his supervisor learned of his employment with NBC and his resulting ineligibility for the position (as it was part of a program designed for those who made under $6,000 a year) and asked him to resign. In early 1982, DeForest was hired to appear on the new show "Late Night with David Letterman". His late-blossoming television career began with a New York University student film project called "King of the Zs", by future Letterman writers Stephen Winer and Karl Tiedemann, who brought him along when they joined the "Late Night" writing staff. The "Associated Press" noted: "DeForest's gnomish face was the first to greet viewers when Letterman's NBC show debuted on February 1, 1982, offering a parody of the prologue to the Boris Karloff film "Frankenstein". 'It was the greatest thing that had happened in my life,' he once said of his first Letterman appearance." On "Late Night", DeForest played the role of Larry "Bud" Melman. "Late Night" talent coordinator Sandra Furton described him as a "mascot", but Melman had no real fixed or defined role on the show. He was simply an older, short, portly man with thick black-framed glasses who was seen relatively frequently, especially in the early years. In the first few years of the show, the Melman character was somewhat of an entrepreneur, appearing in ads for "Melman Bus Lines" as well as for "Mr. Larry's Toast On A Stick" ("Bread's answer to the Popsicle!").
