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.

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 dental surgery.
