Addison Cairns Mizner (December 12, 1872-February 5, 1933) was an American architect who played a pivotal role in shaping the architectural landscape of South Florida. His signature Mediterranean Revival and Spanish Colonial Revival styles are evident in the region's design to this day. Mizner was born in Benicia, California, and his early years were influenced by his travels with his father, a lawyer and diplomat. Mizner's architecture career flourished in the 1920s when he became Florida's premier architect, designing more than fifty Palm Beach villas and Florida mansions for wealthy socialites. His notable works include the Everglades Club and The Boca Raton resort and club. His designs were not just buildings but comprehensive environments, incorporating interior and garden design, which he facilitated through his firm, Mizner Industries. Despite his lack of formal university training, Mizner's innovative and exacting approach left a lasting imprint on South Florida's aesthetic, transforming its ambience and becoming the region's architectural hallmark.
