French Toast is apparently named after its inventor, Joseph French of Albany, NY, and has nothing to do with France.
Update: Grant Barrett wrote to point out that the OED has a citation for french toast which precedes the "French's toast" story by some 64 years. A little digging found the story and several others on the Food Network web site. It still appears to be an American invention, though.
