Erna Hoover, born in Irvington, New Jersey, made key contributions to the system architecture of the first electronic telephone central office developed by Bell Labs. This architecture used “stored program control” to achieve an unprecedented level of flexibility.
Hoover received a B.A. from Wellesley College in classical and medieval philosophy and history in 1948 and a Ph.D. from Yale University in philosophy and foundations of mathematics in 1951. She was a professor in Swarthmore College from 1951 to 1954, when she joined Bell Labs. Later, she worked on the development of the Safeguard Anti-Ballistic Missile System and subsequently became the first woman to head a technical department.
