Activity in that area began at least a year, and probably more, before Mizner's announcement. Land acquisition, tens of thousands of acres, was the largest part. But it is hard not to see Mizner's hand in the incorporation of Boca Raton in 1924; the city immediately appointed him Town Planner. The Mizner Development Company was incorporated in 1925, and promptly issued $5 million of stock, which was fully subscribed in less than a week. $500,000 was reserved for the "average Floridian"; the remainder was purchased by, as Addison called them, "noted personages", all with a Palm Beach connection: Lytle Hall, Harold Vanderbilt, J. Leonard Repogle, the Duchess of Sutherland, Rodman Wanamaker, Paris Singer, Irving Berlin, Madame Frances Alda, W. C. Robinson, H. H. Rodgers, D. H. Conkling, A. T. Herd, Porte, William Kissam Vanderbilt II, Elizabeth Arden, Jesse Livermore, Clarence H. Geist, and T. Coleman du Pont as chairman. Addison's brother Wilson also appears on the list of investors, but he had little to invest.
