Marie-Hélène Schwartz (1913 – 5 January 2013) was a French mathematician, known for her work on characteristic numbers of spaces with singularities.
She married another Jewish mathematician, Laurent Schwartz, in 1938, and both soon went into hiding while the Nazis occupied France.
After the war, she taught at the University of Reims Champagne-Ardenne and finished a thesis on generalizations of the Gauss–Bonnet formula in 1953.
[1][3] A conference was held in her honour in Lille in 1986, and a day of lectures in Paris honoured her 80th birthday in 1993, during which she presented a two-hour talk herself.
She continued publishing mathematical research into her late 80s.
