Erna Schneider Hoover earned a B.A.
with honors in medieval history from Wellesley College, and later a Ph.D.
in the philosophy and foundations of mathematics from Yale University.
In 1954, Erna Schneider Hoover started work as a researcher at Bell Laboratories
in New Jersey, where she created a computerized telephone switching system.

ever issued (Patent #3,623,007, Nov. 23, 1971). Bell Labs made her their
first female supervisor of a technical department.
