"We were three sisters who not only took turns blazing trails and marking courses for one another, we were each other's secret shares. The co-keepers of each other’s memories. I have no words to explain the feeling of suddenly being the only remaining direct offspring of Richard and Andrea Simon. They touched everyone they knew and those of us they’ve left behind will be lucky and honored to carry their memories forward. With great and eternal love and respect," she continued.
In 1991, Lucy received a Tony nomination for her work in the Broadway musical "The Secret Garden."

Meanwhile, in 1962, the former talented singer Joanna made her debut at the New York City Opera as Mozart’s Cherubino, and she continued her career with the New York Philharmonic, the Vienna Philharmonic and the Pittsburgh Symphony Orchestra.
Joanna was a former arts correspondent for PBS’s "MacNeil-Lehrer News Hour" until 1992 and then found a career in real estate.
