Salisbury Steak has nothing to do with South Africa, or even the 13th
century city in England. It was invented by a U.S. physician, J. H.
Salisbury, to encourage a lo-carb diet for losing weight. The
Miriam-Webster dictionary says the term has been in use in the U.S.
since 1897.

Salisbury Steak is made from ground beef. Swiss Steak is made from a
tough cut of beef that has been "Swissed", that is, pounded or run
through bladed rollers to tenderize it.
