L. Joslyn personified the American dream. In 1893 when Marcellus
was a student at Harvard Law School, he built his own telephone
line to his parents' home. He then established Citizens Telephone.
In 1910, Marcellus opened a second company, Joslyn Mfg. &
Supply Co., to manufacture telephone pole line hardware.
In the early 1950's, Joslyn worked with several airframe manufacturers
and the Lightning and Transient Institute of Minneapolis to
address post WW II concerns of lightning and electro-magnetic
pulse (EMP) impacts on aircraft HF radios. The resulting designs,
which are still used today, lead Joslyn into the manufacture
of specialty Gas Discharge Tube (GDT) products. In 1964, the
modern-day Joslyn Electronics Systems Corporation (JESC) opened
at the Santa Barbara Research Park in California.
the next several years, Joslyn
recruited the best electronics engineers to design and develop
full product lines. After
gaining recognition as the leading supplier of aircraft lightning
arresters, Joslyn quickly gained recognition as the leader
surge and transient protection for power, communications,
transportation and industrial process control.
