Wikipedia states that Isabel Ebel (1908-1992) was the first woman student at MIT and NYU studying aeronautical engineering.Her photo appears on page 68.   She was a member of the Women's Rifle Team and Cleofan Society.
Ebel earned her aeronautical engineering at MIT in 1932. She assisted Amelia Earhart  when she was planning one of her record-breaking flights. Ebel continued her study at New York University. It was said that she was only accepted because Earhart interceded with the admission staff on her behalf. In 1939 war broke out in Europe and she gained a job at the Grumman Aircraft Corporation where she helped with several aircraft but in particular the Grumman XF5F Skyrocket.
