Argentine real-estate developer Eduardo F. Costantini is dedicated to promoting art and culture in Latin America. The 70-year-old is the founder and chairman of the Museo de Arte Latinoamericano de Buenos Aires (MALBA), which is unwritten by Costantini’s namesake foundation. In 2001, Costantini donated over 220 works of Latin American art to the museum by artists including Diego Rivera and Frida Kahlo. Costantini has developed some of the most iconic buildings in Buenos Aires, including the Catalinas Plaza in 1995 and the Alem Plaza in 1998. In 2009, he started work on Oceana Key Biscayne in Miami, a project completed in 2015, with prices for condominiums topping out at $19 million. The tower’s outdoor space naturally includes two sculptures by Jeff Koons, both of which residents have an ownership stake in.
