Eventually though, Mr. Kaufmann decided on Mr. Neutra, a younger architect known for his more Modernist approach. Mr. Neutra had worked under Mr. Wright before starting his own practice in 1930.
“Kaufmann’s son Edgar, Jr., an architect, historian and fond disciple of Wright’s, wanted his father to engage Wright again to design the new Palm Springs winter house, but the senior Kaufmann, while a warm admirer of Wright, wanted for the desert house a greater feeling of lightness and openness than Wright had imparted” to Fallingwater, writes Thomas S. Hines in the book, “Richard Neutra and the Search for Modern Architecture.”
Mrs. Kaufmann helped with the setup by lying down in the garden to block the pool light, and a strange shadowy figure on the grass is the family dog, which sneaked into shot, according to Leo Marmol, managing partner at the architectural restoration firm Marmol Radziner, which worked on a restoration of the home in the 1990s. He calls the shot “one of the seminal definitions of Modern architecture in California,” noting that “it captured the Modern fantasy.”
