Lester Townes "Bob" Hope (né Leslie Townes Hope; May 29, 1903 – July 27, 2003) was an American comedian, actor, entertainer and producer with a career that spanned nearly 80 years and achievements in vaudeville, network radio, television, and USO Tours. He appeared in more than 70 short and feature films, starring in 54, including a series of seven Road to ... musical comedy films with Bing Crosby as his partner.

Hope hosted the Academy Awards ceremony a record 19 times. He also appeared in many stage productions and television roles and wrote 14 books. The song "Thanks for the Memory" was his signature tune. He was praised for his comedic timing, specializing in one-liners and rapid-fire delivery of jokes that were often self-deprecating. Between 1941 and 1991, he made 57 tours for the United Service Organizations (USO), entertaining military personnel around the world. In 1997, Congress passed a bill that made him an honorary veteran of the Armed Forces.

Hope was born in the Eltham district of southeast London. He arrived in the United States with his family at the age of four, and grew up near Cleveland, Ohio. He became a boxer in the 1910s but moved into show business in the early 1920s, initially as a comedian and dancer on the vaudeville circuit before acting on Broadway. He began appearing on radio and in films starting in 1934. Hope retired from public life in 1999 and died in 2003, at 100.

Leslie Townes Hope was born on May 29, 1903, in Eltham, County of London (now part of the Royal Borough of Greenwich), in a terraced house at 44 Craigton Road in Well Hall, where there is now a British Film Institute 'Centenary of British Cinema' commemorative plaque in his memory. He was the fifth of seven sons of William Henry Hope, a stonemason from Weston-super-Mare, Somerset, and Welsh mother Avis (née Townes), a light opera singer from Barry, Vale of Glamorgan, who later worked as a cleaner. William and Avis married in April 1891 and lived at 12 Greenwood Street in Barry before moving to Whitehall, Bristol, and then to St George, Bristol. The family emigrated to the United States aboard the SS Philadelphia, passing through Ellis Island, New York on March 30, 1908, before moving on to Cleveland.

From age 12, Hope earned pocket money by singing, dancing, and performing comedy on the street. He entered numerous dancing and amateur talent contests as Lester Hope, and won a prize in 1915 for his impersonation of Charlie Chaplin. For a time, he attended the Boys' Industrial School in Lancaster, Ohio, and as an adult donated sizable sums of money to the institution. He had a brief career as a boxer in 1919, fighting under the name Packy East. He had three wins and one loss, and he participated in a few staged charity bouts later in life. In December 1920, 17-year-old Hope and his brothers became US citizens when their British parents became naturalised Americans. He legally changed his name from Leslie to Lester.

In 1921, while working as a lineman for a power company, Hope was assisting his brother Jim in clearing trees when a tree crashed to the ground, crushing his face; the accident required reconstructive surgery, which contributed to his later distinctive appearance. In his teens, he had also worked as a butcher's assistant as well as a brief stint at Cleveland's Chandler Motor Car Company in his early 20s.

Hope and his girlfriend later signed up for dancing lessons, encouraged after they performed in a three-day engagement at a club. Hope then formed a partnership with Lloyd Durbin, a friend from the dancing school. Silent film comedian Fatty Arbuckle saw them perform in 1925 and found them work with a touring troupe called Hurley's Jolly Follies. Within a year, Hope had formed an act called the "Dancemedians" with George Byrne and the Hilton Sisters, conjoined twins who performed a tap-dancing routine on the vaudeville circuit. Hope and Byrne also had an act as Siamese twins; they sang and danced while wearing blackface until friends advised Hope that he was funnier by himself.

In 1929, Hope informally changed his first name to "Bob". In one version of the story, he named himself after racecar driver Bob Burman. In another, he said that he chose the name because he wanted a name with a "friendly 'Hiya, fellas!' sound" to it. In a 1942 legal document, his legal name appears as Lester Townes Hope. After five years on the vaudeville circuit, Hope was "surprised and humbled" when he failed a 1930 screen test for the RKO-Pathé short-subject studio at Culver City, California.
