Cosby was born and raised in Philadelphia, Pennsylvania. He is one of four sons born to Anna Pearl (née Hite), a maid, and William Henry Cosby Sr., who served as a sailor in the U.S. Navy. During much of his early childhood, Cosby's father was away in the U.S. armed forces and spent several years fighting in World War II. As a student, he described himself as a class clown. Cosby was the captain of both the baseball team and the track and field team at Mary Channing Wister Public School in Philadelphia, as well as the class president. Early on, though, teachers noted his propensity for clowning around rather than studying. At Fitz Simmons Junior High, Cosby began acting in plays as well as continuing his devotion to playing sports. He went on to Central High School, an academically challenging magnet school, but his full schedule of playing football, basketball, baseball, and running track made it hard for him. In addition, Cosby was working before and after school, selling produce, shining shoes, and stocking shelves at a supermarket to help out the family. He transferred to Germantown High School, but failed the tenth grade. Instead of repeating, he got a job as an apprentice at a shoe repair shop, which he liked, but could not see himself doing the rest of his life. Subsequently, he joined the Navy, serving at the Marine Corps Base Quantico, Virginia, Naval Station Argentia, Newfoundland and at the Bethesda Naval Hospital in Maryland.
While serving in the Navy as a Hospital Corpsman for four years, Cosby worked in physical therapy with some seriously injured Korean War casualties, which helped him discover what was important to him. Then he immediately realized the need for an education, and finished his equivalency diploma via correspondence courses.^[11] He then won a track and field scholarship to Philadelphia's Temple University in 1961–62, and studied physical education while running track and playing fullback on the football team.
As Cosby progressed through his undergraduate studies, he continued to hone his talent for humor, joking with fellow enlistees in the service and then with college friends. When he began bar tending at the Cellar, a club in Philadelphia, to earn money, he became fully aware of his ability to make people laugh. He worked his customers and saw his tips increase, then ventured onto the stage.

Cosby left Temple to pursue a career in comedy, though he would return to collegiate studies in the 1970s. He lined up gigs at clubs in Philadelphia and soon was off to New York City, where he appeared at The Gaslight Cafe starting in 1962.  He lined up dates in Chicago, Las Vegas, San Francisco, and Washington, D.C., and elsewhere. He received national exposure on NBC's The Tonight Show in the summer of 1963 which led to a recording contract with Warner Bros. Records, who released his debut LP Bill Cosby Is a Very Funny Fellow...Right!, the first of a series of popular comedy albums, in 1964.
While many comics were using the growing freedom of that decade to explore controversial, sometimes risqué, material, Cosby was making his reputation with humorous recollections of his childhood. Many Americans wondered about the absence of race as a topic in Cosby's stories. As Cosby's success grew he had to defend his choice of material regularly; as he argued, "A white person listens to my act and he laughs and he thinks, 'Yeah, that's the way I see it too.' Okay. He's white. I'm Negro. And we both see things the same way. That must mean that we are alike. Right? So I figure this way I'm doing as much for good race relations as the next guy."
Cosby remains an actively touring stand-up comedian, performing at theaters throughout the country.
