Who invented "frequency-hopping spread spectrum" and an element of the modern day Wi-Fi?

Hedy Lamarr, the famous actress, was born in Vienna, Austria-Hungry in 1914. At 19 she married an Austrian military arms merchant and munitions manufacturer. She attended many meetings with him, as his wife, and learned a lot about the use of weapons. They eventually divorced and she left her country for the U.S.

During World War II, Hedy used her weapons knowledge to come up with an idea on how to track and jam a torpedo. In order to develop a design for this idea she asked, George Antheil, a composer and pianist to help her. By using a music tube from a player piano they drafted a design linked to radio signals which could potentially be used to help the Allied war efforts. This design was referred to as a “frequency-hopping system”.

A patent was filed and granted by Lamarr and Antheil in 1942. They both presented the design to the U.S. Navy who classified the designed and developed long range plans to perfect and implement. Eventually, in 1962, the design was perfected is and now known to be the major element in the modern day CDMA, Wi-Fi networks and Bluetooth technology.
