Who gave the Bermuda Triangle its name?

Noted and now deceased Fishing commentator Vincent (Gadabout) Gaddis is credited with popularizing the phrase- Bermuda Triangle. Mr. Gaddis was a very popular angling author and ran both radio and TV shows on fishing- one called the Flying Fisherman. He was known to Fish out of the front hatch of a Republic Seabee amphibious plane- and was photographed doing this. Writing as Vincent Gaddis- he did a book on the subject of the Triangle which popularized the name- I don't know if he ever fished in the area!
