Born and raised in Astoria, Bennett began singing at an early age.
He fought in the final stages of World War II as an infantryman with the U.S. 
Afterwards, he developed his singing technique, signed with Columbia Records, and had his first number-one popular song with "Because of You" in 1951. Several top hits such as "Rags to Riches" followed in the early 1950s.
Bennett then further refined his approach to encompass jazz singing.
In 1962, Bennett recorded his signature song, "I Left My Heart in San Francisco".

His career and his personal life then suffered an extended downturn during the height of the rock music era.

Bennett staged a comeback in the late 1980s and 1990s, putting out gold record albums again and expanding his audience to the MTV Generation while keeping his musical style intact.
He remains a popular and critically praised recording artist and concert performer in the 2010s.
Bennett has won 17Grammy Awards (including a Lifetime Achievement Award, presented in 2001)
