The New York Times: Cathleen Morawetz, Mathematician With Real-World Impact, Dies at 94.
“Cathleen S. Morawetz, a mathematician whose theorems often found use in solving real-world engineering problems, died on Tuesday at her home in Manhattan. She was 94.
Her death was reported by New York University, where she had been a professor.
