Cornell-Dubilier Electric Corporation
has been manufacturing capacitors for more than a century - 109 years as of this
writing to be more precise. That is utterly amazing, especially since they still
use the name of the company founder, William Dubilier. In 1933, they merged with
Cornell Radio to form Cornell Dubilier Electronics (CDE). If you have been in the
electronics field for a while, you no doubt have heard of their capacitors. In fact,
William Dubilier was the inventor of mica-based capacitors. According to this
obituary in a 1969 issue of Radio-Electronics magazine (he died on July 25, 1969),
Mr. Dubilier held 600 patents. I found a newspaper obit that claims Dublilier
was offered, but did not accept, a knighthood and pension for life by the British
as a reward for inventing a submarine detection device used in World War I by the
French and British governments.

Inventor Dies at 81
Palm Beach, Fla. (AP) - Inventor William Dubilier, who developed several systems
of wireless telephony and telegraphy and held over 300 U.S. patents, died Friday
on his 81st birthday.
Two rooms at the Smithsonian Institution in Washington, D.C., are devoted to
his models and equipments.
Dubilier invented the mica condenser universally used in broadcasting stations
and for high frequency equipment and a submarine detection device used in World
War I by the French and British governments. For it Dublilier was offered, but did
not accept, a knighthood and pension for life by the British.
In 1914-15, he supplied the U.S. government the first wireless communications
system for airplanes. In 1910 he pioneered in the adaption of X-ray equipment for
