Clarence H. Geist was born in 1866 on a farm in LaPorte, Indiana. After education at a “normal school” (teacher’s college), he made a living selling horses. He returned to Chicago to work for the Rock Island Railroad, entered the real estate market, and eventually joined Rufus and Charles G. Dawes in the development of a gas and electric utilities company. (Charles Dawes was to serve as vice president in the late 1920s, and the Dawes brothers took over the management of the Mizner Development Corporation in mid 1926.) Geist married Florence Hewitt, and in 1905 they moved to Philadelphia and Geist began investing in utilities, gaining control of the Philadelphia Suburban Water Company. It was his association with the water supply that earned him the nickname “Waterboy.”
Geist had become a snowbird in Palm Beach in the early 1920s. He built a beautiful house, La Claridad, on Golf View Road designed by Marion Syms Wyeth, the original architect of Mar-a-Lago. One of the legends about Geist is that he built the Boca Raton Club because he had been blackballed from the Everglades Club due to his uncouth behavior. This is not true—he was a member of that august body and many others as well. He also became an investor in the Mizner Development Corporation’s “Boca Raton” project.
