Ida Barney (November 6, 1886 – March 7, 1982) was an American astronomer, best known for her 22 volumes of astrometric measurements on 150,000 stars.

There, she was a member of Phi Beta Kappa and Sigma Xi, national honor societies for students.

[6] Despite this influence, she developed several methods that increased both the accuracy and speed of astronomic measurements, including the use of a machine that automatically centered the photographic plates.

Under her direction, the measurements of the photographic plates were completed at the IBM Watson Scientific Laboratory using a new electronic device that advanced the reduction of eye strain and increased accuracy.

[2] The Women's Centennial Congress was organized by Carrie Chapman Catt, November 25–27, 1940, to celebrate a century of female progress.

To demonstrate those advances, 100 "successful women" were invited to represent the respective fields of study in which they were working in 1940, but that would have been impossible for them in 1840.
