Hedy Lemarr - inaccurate claim
The existing page states "Hedy Lamarr was the inventor of frequency-hopping technology" which is untrue. There were many prior patents, for example Willem Broertjes patent US1869659 from 1929, and Nikola Tesla described a method of discharging different value condensers into a resonant coil at periodically-recurring intervals via a rotating wheel in his 1903 patent US723188... he didnt use the phrase "frequency hopping" but the concept was documented in 1903. Marconi and Tesla beat Lamarr by 4o years and its known that Germany used basic frequency hopping communications during WW1.

Whilst its clear that a lot of work has gone into creating this page, a task I would not want to repeat, I despise plagiarism and would like to see the inappropriate credit removed and her patent clarified - the Lamarr/Antheil 1941 patent 2292387 was a combination of frequency hopping radio, using paper tape driving switched capacitors and an associated escapement system for the remote control of a torpedo rudder. It was demonstrably NOT the first time frequency hopping had been described in a patent.
