Hans Pfyffer von Altishofen (German: [ˈpfʏfɐ fɔn ˈʔaltɪʃoːfən]; 28 March 1866 – 5 April 1953) abbreviated as Hans Pfyffer was a Swiss businessman, hotelier, politician and diplomat who served as Minister to the Mission of Switzerland to Poland in Warsaw from 1921 to 1923.

Born into a well established Patrician family, Pfyffer became a serial entrepreneur, primarily in the hospitality industry.

In 1892, he was among the co-founders of Berneralpen Milchgesellschaft (milk powder), among César Ritz and Auguste Escoffier.

After completing his Matura, Pfyffer began to study medicine, but abandoned his plans after his father died and ultimately entered the family business, the Grand Hotel National in Lucerne.

He was a director of various enterprises in central Switzerland including power plants, paper mills and the Vitznau–Rigi Railway.

[6] Pfyffer was a passionate promoter of tourism in the Lucerne region, and through his efforts managed to preserve the Grand Hotel National with little damage during the two world wars and the intervening financial crisis.
