She began her collecting with works by Picasso, Fernand Léger, and Jean Dubuffet acquired from Pace Gallery, where gallery owner Arne Glimcher guided her and introduced her to the New York art scene. Through Glimcher, Fisher Landau met many luminaries of the period including Andy Warhol, Ed Ruscha, Jasper Johns, and Mark Rothko, befriending them, visiting them at the studio, and acquiring works that appealed to her.
She was also a great supporter of institutions, and joined the board of the Whitney Museum of American art in the mid-1980s where she would spend the coming decades endowing the Whitney Biennial exhibitions, one of the country’s premiere stages for emerging American artists. Fisher Landau preserved her legacy for the future and her connection with the museum when, in 2010, she donated almost 400 works from her collection.
One of the earliest paintings she acquired, in 1968, was Picasso’s 1932 painting Femme à la Montre. It remained in her collection for over five decades. A portrait of Marie-Thérèse Walter, Picasso’s famed “golden muse”. It was painted just following his first major retrospective at Galeries Georges Petit in Paris. He had met Walter a few years earlier in 1927, when she was seventeen, and he was 45, and they began a now-legendary affair, while he was still married to his first wife, Olga Khokhlova. The work is estimated to bring in over $120 million.
