From Wikipedia: "Stengel's retirement, announced on August 30, 1965, followed a fall at Shea Stadium, in which he broke his hip."
From Baseballlibrary.com: "In July of 1965, leaving a party at Toots Shor's, Stengel fell and broke his hip. It was impossible to manage anymore, and in August, out of the hospital and leaning on a cane, he made his formal farewells."
