What spy was allegedly captured by a plan involving the Eiffel Tower?

Mata Hari, the famous exotic dancer and WWI spy, was allegedly captured through intelligence operations that may have involved monitoring from the Eiffel Tower (which was used for radio intercepts). She was executed in 1917 for espionage. Anthony Blunt was a Cold War spy, Nathan Hale was an American Revolutionary spy, and Ian Fleming was a naval intelligence officer who later wrote James Bond - none were captured via Eiffel Tower operations.
