Hedy Lamarr developed mechanical intuition by dismantling music boxes and clocks at age five.

The sinking of the SS City of Benares motivated Lamarr to invent unjammable torpedo technology.

Lamarr and George Antheil used player piano rolls to synchronize eighty-eight different radio frequencies.

The Navy rejected the original patent because they found the player piano analogy impractical.

Lamarr raised twenty-five million dollars for the war effort by selling kisses and war bonds.

Frequency hopping logic eventually became the foundational architecture for modern Wi-Fi, Bluetooth, and GPS.
