In 1966, the vacated studio space was converted into the Vanderbilt Athletic Club, a sports club named for the hall just below. Founded by Geza A. Gazdag, an athlete and Olympic coach who fled Hungary amid its 1956 revolution, its two tennis courts were once deemed the most expensive place to play the game—$58 an hour—until financial recessions forced the club to lower the hourly fee to $40. Club amenities included a nylon ski slope, a health club facility and sauna, and spaces for golf, fencing, gymnastics, and ballet practice. Gazdag's business was evicted from Grand Central in 1976, amid a lease dispute. In 1984, the club was purchased by real estate magnate Donald Trump, who discovered it while renovating the terminal's exterior. In 2009, the MTA planned a new conductor lounge in the space, and terminated Trump's lease that year. It divided the space into three floors, with the lounge on the original third floor. A single tennis court was added on the new fourth floor in 2010, along with two practice alleys on the new fifth floor. Trump found the new space too small to release, and so the current Vanderbilt Tennis Club operates independent of Trump.
