Yes, in english language. Other languages have/had different names, if they even knew it at this point. There was of course a reason why the @ was on the english keyboard-layout, but it was a very different reason from the later usage as location/user-reference. Point is, if e-mail would have been invented in a different culture, there would be a good chance that the symbol wasn't even on their keyboard at the time and a different symbol would likely have been used.
