At the very least, Tesla deserves credit for the improved transmitter design
which allowed significantly higher levels of radio-frequency power output to
be achieved.  Some historians recognize Reginald Fessenden in 1900, others
say it was Ferdinand Braun, after a hastily improvised demonstration in
September 1898.  In reality, Nikola Tesla revealed the basic technique for
improving transmitter performance with a series of U.S. patents, starting
with his "System of Electric Lighting" Patent No. 454,622, dated June 23,
1891, the accompanying drawing of which shows an energy-storage capacitor
and a discharge device on the primary side of a resonance transformer.
