The specific mechanism — disguised as a maid, or in possession of her own maid’s identity papers, or walking past guards who didn’t recognize her — has appeared in different versions in different sources. The Jewish Women’s Archive, which has published a careful entry on Lamarr, does not assert a specific escape mechanism, noting that accounts differ. The biographies by Ruth Barton and Stephen Michael Shearer, both serious scholarly works, treat the escape story with the appropriate hedging that direct evidence warrants.
What Lamarr gained from the marriage, and from the dinner parties and conversations at Mandl’s table, was a working understanding of the arms industry — specifically of the ways in which military technology was designed and discussed by the people who produced it. She was not an engineer. She did not have engineering credentials or formal technical training. But she understood the problem of radio jamming of torpedo guidance systems because she had heard that problem discussed by people who spent their professional lives thinking about it. This was not nothing. It was, in the specific context of her later collaboration with Antheil, exactly enough.
## A Studio Career Examined
The MGM contract that made Hedy Lamarr gave her security and removed her agency. That exchange — security for control — was the basic deal the studio system offered to everyone, and it was a deal that hurt women more than men because men were more likely to negotiate its terms successfully, or to find ways around it, or to be offered the kind of roles that expanded over time rather than contracted.
