Hildegard Rothe-Ille

Hildegard Rothe-Ille, born Hildegard Ille, (1899–1942), was a German mathematician.

Career She was one of Issai Schur’s doctoral students. According to Alexander Soifer, “Van der Waerden walked away from Ramseyan prehistory. Issai Schur, on the other hand, continued to produce Ramseyan mathematics, and moreover directed and inspired his PhD students Richard Rado, Hildegard Ille and Alfred Brauer to do the same.”

She received her doctorate in mathematics in 1924. Beginning on April 1, 1925, she was a year-long scholarship holder at the Kaiser Wilhelm Institute for Physics, which was headed by Albert Einstein at the time. She was the only woman to receive a scholarship from that institute in that academic year, and she received a higher scholarship than her male counterparts did.

She and Erich and their son Erhard left Nazi Germany and arrived in Zürich in 1937. Erich went to the United States after this, and Hildegard and Erhard followed in 1938.
