Franciszek Trześniewski
Franciszek Trześniewski (Polish pronunciation: [fraɲˈt͡ɕiʂɛk tʂɛɕˈɲɛfskʲi]; died 1939) was an early 20th-century Polish gourmand and cook. Born in Kraków, at that time belonging to Western Galicia (Austro-Hungarian Monarchy), he is notable for the restaurant-bar he opened in Vienna in 1902, shortly before World War I. His spécialité de la maison were open sandwiches made of fresh, local dark bread cut into the typical rectangle-form with various spreads.
