From Edward Winter (https://www.chesshistory.com/winter/extra/swiss.html):
"The books call 1 f4 f5 2 e4 the Swiss Gambit, but this is a misnomer resulting from a misunderstanding. These opening moves, three consecutive improbabilities, attracted considerable international attention after the theoretician Alexander Wagner (1868-1942) published an article on pages 35-36 of the February 1912 Schweizerische Schachzeitung (see extract above). Entitled ‘A New Gambit."
