Life

edit

She was born in Kilmore, County Wexford, Ireland. Her parents were Ellen Dunne and Walter Gough. She attended the local St John of God's primary school.[1] She emigrated to Texas in 1909 with a group of young Irish women, and joined the Sisters of Charity of the Incarnate Word, taking vows as Mary de Lellis in 1911.[2]

Career

edit

While working as a high school teacher, she studied at the Catholic University of America. She graduated in 1920, earned a master's degree in 1923, and completed her PhD from the same university in 1931.[2] Her PhD dissertation was entitled On the condition for the existence of triangles in and circumscribed to certain types of the rational quartic curve and having a common side and supervised by Aubrey E. Landry.[2][3]

She taught mathematics at Incarnate Word College from 1920 to 1943.[2] In 1953, she coined the term "mathephobia" based on her observations of her students.[4]

In 1944, she left teaching due to health issues and returned to Texas where she worked as an accountant at a local hospital in Fort Worth. She retired in 1964.[1]
