For unknown reasons, Tesla rents another room at the Hotel Pennsylvania and makes it his primary residence while continuing to rent the room at Hotel Marguery. He confided in Kenneth Swezey, telling him that the room at Hotel Marguery was for meeting "special" friends and acquaintances.
Katharine McMahon Johnson was, according to some accounts, the only woman Tesla ever loved. She was the wife of Tesla's lifelong friend, Robert Underwood Johnson. Though the two often exchanged flirtatious letters, their relationship was totally platonic. Not forgetting Tesla even at death, she charged Robert to keep in close touch with him always.
For unknown reasons, Tesla relocates his office from 8W 40th St. to 350 Madison Ave. By 1928, maintaining an office had become too burdensome and it was closed for good.
