Abstract :
A review of the history and bibliography of the capacitor art of the 18th, 19th, and 20th centuries, prior to the founding of the IRE in 1912, compared to the explosive developments of the fifty years to 1962, shows the evolutionary nature of the advances in capacitor engineering. The dependence and parallelism of capacitor engineering with the mainstream of development in the basic sciences are clear and are further indicated for the future.
