This day in 1973: Singer Bobby Darin died aged at the age of 37. One of the first teen idols, he had the 1959 No.1 with ‘Dream Lover’ plus 20 other US Top 40 hits during the 60s including ‘Mack the Knife’, (Grammy Award for Record of the Year in 1960). Darin travelled with Robert Kennedy and worked on the latter’s 1968 presidential campaign. He was with Kennedy the day he travelled to Los Angeles on June 4, 1968 for the California Primary. Darin was at the Ambassador Hotel later that night when Kennedy was assassinated.

Darin suffered from poor health his entire life. He was frail as an infant and, beginning at age eight, was stricken with recurring bouts of rheumatic fever that left him with a seriously weakened heart. During his first heart surgery, in January 1971, he had two artificial valves implanted in his heart. He spent most of that year recovering from the surgery.

During the last few years of his life, he was often administered oxygen during and after his performances on stage and screen.

After failing to take antibiotics to protect his heart before a dental visit, Darin developed sepsis, an overwhelming systemic infection. That further weakened his body and affected one of his heart valves. On December 11, he checked himself into Cedars of Lebanon Hospital in Los Angeles for another round of open-heart surgery to repair the two artificial heart valves he had received in January 1971. On the evening of December 19, a five-person surgical team worked for over six hours to repair his damaged heart. Shortly after the surgery ended in the early morning hours of December 20, 1973, Darin died in the recovery room without regaining consciousness. He was 37 years old.
