Ellas Otha Bates, known professionally as Bo Diddley, was an American guitarist and singer who played a key role in the transition from the blues to rock and roll. He influenced many artists, including Buddy Holly, Elvis Presley, the Beatles, the Rolling Stones, the Animals, George Thorogood, Syd Barrett, and the Clash.

Rock and roll is a genre of popular music that evolved in the United States during the late 1940s and early 1950s. It originated from African American music such as jazz, rhythm and blues, boogie-woogie, electric blues, gospel, jump blues, as well as country music. While rock and roll's formative elements can be heard in blues records from the 1920s and in country records of the 1930s, the genre did not acquire its name until 1954.
