No one founded the Bermuda Triangle. The concept of the "Bermuda Triangle" (or Devil's Triangle) as a region of mysterious disappearances is a modern legend, not a formal geographic or scientific entity with a founder.
The term "Bermuda Triangle" was coined by writer Vincent Gaddis in a 1964 article for Argosy magazine titled "The Deadly Bermuda Triangle." The vertices are typically defined as Miami (Florida), Bermuda, and San Juan (Puerto Rico).
The "Bermuda Triangle" is a cultural phenomenon fueled by sensationalism, not a discovery or invention attributable to a founder.
