the apherical audion the gateway to the golden age of radio

One of the more colorful pioneers
of early wireless was Lee de Forest,
and his most noted invention
is the Audion, more commonly referred
to as the triode. Arguably, the triode was
the gateway invention that allowed radio
to become commercially viable.
De Forest was born in 1873 in Council
Bluffs, Iowa, and received his Ph.D. in
1899 from Yale [1] his thesis topic was
“Reflections of Hertzian Waves from
the Ends of Parallel Wires.” His first job
was with Western Electric in Chicago,
where he became friends with Edwin
Smythe. On their own time, these two
entrepreneurial engineers worked
together to develop improved methods
of detecting wireless signals. In 1901,
de Forest founded the Wireless Telegraph
Company of America to make
wireless transmitters and receivers.
