From a New York Times obit by Richard Sandomir headlined “Sheila Tobias, Who Defined ‘Math Anxiety,’ Dies at 86”:
When Sheila Tobias finished her freshman year at Radcliffe College in 1954, her professor in a natural sciences course congratulated her on her performance. But for many years she was troubled that he had not encouraged her to take more science classes. When she finally asked him, he said that her limited science background had already made her ineligible for a science career.
