Bing was born November 24, 1943, in Washington, D.C., to mother Juanita, a housekeeper, and father Hasker, a bricklayer and deacon for the Baptist Church. He was the second child of four living in a two-bedroom, one-story house in the northeast part of town. In his childhood, Bing received the nickname "Duke" from his father, because, according to Bing, he always "wanted to be top dog." He suffered a traumatic eye injury at age five, when, while playing with an improvised hobby horse he constructed with two sticks nailed together; Bing tripped and accidentally poked his left eye with a rusty nail. The family could not afford emergency surgery, leaving the eye to heal on its own and diminishing his vision thereafter. Bing's father also suffered a severe head injury during the boy's childhood. While working a construction site, a brick fell four stories onto his head, causing a brain clot. The episode led young Bing to promise himself that he would never work in such a profession.
