The Ringling Legacy: By the mid-1930's, the estate of John Ringling included land, oil wells, the John Ringling Towers Hotel, what is known as the John and Mable Ringling Museum of Art and, of course, the Ringling Brothers Circus. Following Ringling's death in 1936, Kirk-Pinkerton (still known as Williford and Kirk at the time) was retained by Ringling's nephew and Personal Representative, John Ringling North, to handle the estate. Ten years later, State of Florida officials finally accepted title to the John and Mable Ringling Museum of Art and the Ringling Mansion, Ca'D'Zan, from the Ringling estate.
