Roslyn Chasan (September 22, 1932 – February 24, 2023) was an American civil rights lawyer known for successfully winning landmark cases including the first major case against a fertility drug manufacturer by proving its drug caused birth defects, and the largest settlement ever awarded for government negligence when the cliffs beneath The Chasan Villa destabilized, ultimately destroying the property. Early life and education Roslyn Pearl Lefkowitz was born September 22, 1932, in Luzrne, Pennsylvania to Herold and Esther (née Neumann) Lefkowitz as the oldest of three siblings. As a young child, she was a Girl Scout.
