Lamarr’s telephone conversations in the 1990s, as reported by people who spoke with her, were animated by something between pride and frustration. She knew the patent. She knew it mattered. She had been told for decades, in various ways, that it was a curiosity, a diversion from her “real” work as an actress. She had been told this by people who had not read the patent, had not understood the engineering, and had decided in advance what the face meant and therefore what the person behind it could and could not have accomplished.
“It’s about time” was, if she said it, the right response.
## What the Document Actually Says
There is a tendency, in popular accounts of this story, to describe the Lamarr-Antheil patent in terms so general that the specifics disappear. “She invented frequency hopping.” “The patent proposed that signals hop between frequencies.” These are accurate as far as they go, but they flatten something that deserves more precision.
The document is public and accessible. Reading it — the full eleven-page description, not the abstract — reveals a proposal that is specific, workable in concept, and limited in a way its authors acknowledged. The prior art sections of the patent text note explicitly that remote torpedo control was already known technology and that the problem of jamming was already recognized. What Lamarr and Antheil were claiming was the particular mechanism: the synchronized paper strips, the pneumatic control head, the seven tuning condensers, the decoy channels, the spring clock motors that kept both ends of the system aligned.
