Cathleen Synge Morawetz

Cathleen Synge Morawetz (1923-2017) was a distinguished Canadian-American mathematician who made fundamental contributions to the study of partial differential equations, particularly in the areas of shock waves and aerodynamic flow. Born in Toronto, Ontario, she studied at the University of Toronto and later earned her Ph.D. from Cornell University. Morawetz spent much of her career at the Courant Institute of Mathematical Sciences at New York University, where she became a leading figure in applied mathematics. Her research had significant practical applications in engineering and physics, particularly regarding supersonic flow and the behavior of waves. She was recognized internationally for her rigorous mathematical work and her ability to solve problems of real-world importance. Morawetz received numerous honors, including the National Medal of Science, one of the highest scientific awards in the United States. Her legacy includes not only her mathematical theorems and publications but also her role in mentoring younger mathematicians and advancing women's participation in mathematics and science during the latter half of the 20th century.
