February 26, 1887 – March 3, 1966Frawley's final performance on-screen was in October 1965, making a cameo appearance in Lucille Ball's second television sitcom The Lucy Show with Lucy saying "He reminds me of someone I used to know."
On March 3, 1966, Frawley collapsed of a heart attack while walking down Hollywood Boulevard after seeing a movie. He was dragged to the nearby Knickerbocker Hotel, where he had previously lived for many years, by his male nurse — a constant companion since his prostate cancer operation more than a year before. He was then rushed to the nearby Hollywood Receiving Hospital (now the Hollywood LAPD Precinct) on Wilcox Ave, where he was pronounced dead.
Shortly following his death, Desi Arnaz paid for a full-page ad in the Hollywood Reporter. It had a picture of Frawley, surrounded in black, the dates of his birth and death, and the caption, "Buenas Noches, Amigo!" ("Good Night, Friend!").
Lucille Ball issued the statement: "I've lost one of my dearest friends and show business has lost one of the greatest character actors of all time. Those of us who knew him and loved him will miss him."
Vivian Vance's reaction was reported as shouting out "Champagne for everyone!"
He is buried in the San Fernando Mission Cemetery in Mission Hills, Los Angeles, California.
For his achievements in the field of motion pictures, Frawley was awarded a star on the Hollywood Walk of Fame at 6322 Hollywood Blvd.
Frawley is memorialized in the Lucille Ball-Desi Arnaz Center in Jamestown, New York, which also contains his "Froggie" costume from an episode of I Love Lucy.
