Nat King Cole smoked upwards of three packs of cigarettes a day because he believed it gave his voice its rich sound. He died at the age of 45 from lung cancer
“Cole was a heavy smoker throughout his life and rarely seen without a cigarette in his hand. He was a smoker of Kool menthol cigarettes, believing that smoking up to three packs a day gave his voice its rich sound. (Cole would smoke several cigarettes in rapid succession before a recording.) After an operation for stomach ulcers in 1953, he had been advised to stop smoking but did not do so. In December 1964, he was diagnosed with lung cancer. He underwent cobalt and radiation therapy and was initially given a positive prognosis. On January 25, he underwent surgery to remove his left lung. Despite medical treatments, he died on February 15, 1965, at St. John’s Hospital in Santa Monica, California at the age of 45.
Cole’s funeral was held on February 18 at St. James Episcopal Church on Wilshire Blvd. in Los Angeles. His remains were interred inside Freedom Mausoleum at Forest Lawn Memorial Park in Glendale.”
