Great Quiz! A couple (minor) corrections: -I wouldn't say Frequency Hopping "helped defeat the Nazis". While Hopper and her co-inventor George Antheil got a patent for the idea during World War II, it wasn't implemented in practice until later on.
-While Clara Barton founded the American Red Cross, the Red Cross itself had been founded 18 years before by Henri Dunant. I'm not sure if Barton's own humanitarian efforts had much impact on Dunant's founding of the organization. |
