I ran my own blog from November 2006 till October 2014. All posts are still online, but I don't have time to update it anymore. Please note that all images and media files have been removed when the backup was moved to a new host in early 2016. Enjoy!
Extactly 94 years ago on November 9, 1913, Hedy Lamarr was born in Vienna, Austria. She became an actress, appeared in serveral european movies, emigrated to the U.S. duing the Second World War and started a quite successful Hollywood career.
On August 11, 1942, Hedy Lamarr and composer George Antheil received a U.S. Patent for their frequency hopping concept. Their invention was able to change between 88 frequencies using a piano roll and was intended jam torpedo communication and detection systems.
It was a controversial concept back then which was ahead of both its time and technology. The U.S. military first used their technology during the Cuba blockade in 1962, but their achievements remained mostly unnoticed during the next decades. Only ten years ago, in 1997, the Electronic Frontier Foundation gave Lamarr and Antheil an award for their invention.
Lamarr's frequency-hopping idea can be considered to be the basic communications concept behind todays portable phones and WiFi internet technologies.
She was married six times and died in Altamonte Springs, Florida on January 19, 2000.
