Bobby Darin (born Walden Robert Cassotto, May 14, 1936–December 20, 1973), was an American singer, actor and musician.

Darin performed in a wide range of music genres, including pop, jazz, folk and country. Although unknown to his public, his health was dangerously fragile and strongly motivated him to succeed within the limited lifetime he feared he would, and ultimately did, have.

He was also an actor, singer/songwriter and music business entrepreneur. His wish for a legacy was, "...to be remembered as a human being and as a great performer." Among his many other contributions, he became a goodwill ambassador for the American Heart Association.
