On December 30, 1961, Del Webb opened Del Webb's Sun City, the first planned self-contained retirement community for active seniors in Florida, with a vision of affordable homes, multiple golf courses, restaurants, shopping, and a variety of activities. The name was later changed to Sun City Center to avoid confusion with the nearby community of Sun City. Developed from what had once been a cattle ranch, Sun City Center grew into a thriving community with clubs and activities for many interests, led by dedicated volunteers regarded as friends and neighbors. Delbert Eugene Webb, born May 17, 1899, and died July 4, 1974, founded and developed Sun City Center, Florida. His construction company also built major commercial projects including Madison Square Garden in New York City, the Flamingo Hotel in Las Vegas, and many government, military, and civilian ventures. He also loved baseball and was once a co-owner of the New York Yankees. In 1960 he built his first active adult retirement community in Phoenix, Arizona, naming it Sun City, and later developed two more retirement communities in California and one in Sun City Center, Florida.
