The claim that she invented Wi-Fi, or Bluetooth, or GPS, appears to have originated in a combination of sources: popular science journalism in the late 1990s and 2000s that framed the EFF award as recognizing a direct technological ancestor of specific consumer products; the natural tendency of storytelling to simplify long chains of engineering into single-inventor narratives; and a cultural appetite for the specific story shape of “overlooked woman inventor secretly responsible for technology we use every day.”
That story shape is appealing because parts of it are true. She was overlooked. The concept she helped develop was important. The technology we use every day descends, through many engineering generations, from concepts in the same conceptual family. The falsifying element is “secretly responsible” — the direct-lineage claim that makes the story feel like a revelation but removes from it the engineering history that makes the real story coherent.
The patents most directly ancestral to modern Bluetooth, for example, are held by Ericsson engineers who designed adaptive frequency-hopping protocols in the 1990s. Those engineers are not credited in popular accounts of Lamarr’s invention, because the popular accounts are not designed to credit everyone who contributed to wireless technology. They are designed to tell a particular story about a particular woman. The story is improved, not diminished, by being accurate.
## The Casselberry Years
She retired to Florida in the 1970s and stayed there. Casselberry, where she lived at the end of her life, is a suburb of Orlando — not a glamorous address, not the kind of place that Hollywood mythology locates its former stars. She appears to have chosen it for reasons of privacy and cost rather than for aesthetic appeal. She did not want to be looked at anymore.
