Glenn Gould lived a private life: Bruno Monsaingeon said of him, "No supreme pianist has ever given of his heart and mind so overwhelmingly while showing himself so sparingly."
In 2007, Cornelia Foss, wife of composer and conductor Lukas Foss, publicly claimed that she and Gould had had a love affair lasting several years. She and her husband had met Gould in Los Angeles in 1956. Cornelia was an art instructor who had studied sculpture at the American Academy in Rome; Lukas was a pianist and composer who conducted both the Buffalo Philharmonic Orchestra and the Brooklyn Philharmonic.
After several years, Glenn and Cornelia became lovers. Cornelia left Lukas in 1967 for Gould, taking her two children with her to Toronto, where she purchased a house near Gould's apartment, at 110 St. Clair Avenue West. According to Cornelia, "There were a lot of misconceptions about Glenn, and it was partly because he was so very private. But I assure you, he was an extremely heterosexual man. Our relationship was, among other things, quite sexual." Their affair lasted until 1972, when she returned to Lukas.
As for me, I am extremely asexual.
