Nora Stanton Barney (née Blatch; 30 September 1883 – 18 January 1971) was an English-born American civil engineer, and suffragist.

She studied Latin and mathematics at the Horace Mann School in New York, beginning in 1897, returning to England in the summers.

[2] In the same year, she was the first woman admitted[3] (accepted as a junior member) of the American Society of Civil Engineers (ASCE).

In 1916, she sued the American Society of Civil Engineers (ASCE) for refusing to admit her as a full member, even though she met all requirements.

[7] In 1908, she married the inventor Lee de Forest, and helped to manage some of the companies he had founded to promote his invention and the new technology of wireless (radio).

However, the couple separated only a year later, due largely to de Forest's insistence that Nora quit her profession and become a conventional housewife.
