Gladys Elena Vergara Gavagnin (1928 – 5 July 2016) was a Uruguayan astronomer and professor, known for her calculations on eclipses, made during a time when computers were not capable of them.

[1][2][3][4] Vergara studied physical sciences and astronomy, at a time when both fields were inaccessible for women.

She was part of the first generation of students of the Astronomy Department founded by Dr. Cernuschi in the University of the Republic's Faculty of Humanities and Sciences [es].

[1][2][6] On 18 July 1968, Chilean astronomers Carlos Torres and S. Cofré discovered, at the Cerro El Roble Astronomical Station in Chile, a new main belt asteroid that was provisionally designated 1968 OA1.

[2] Vergara encouraged her students to buy a 10 cm Unitron refracting telescope that was used to inaugurate the Observatory of the Women's Institute of Secondary Education, Batlle y Ordóñez Institute (IBO), of which she was one of the founders in January 1976.
