The Antonina Leśniewska Museum of Pharmacy, a branch of the Museum of Warsaw, was opened on January 26, 1985, thanks to the initiative of Kazimierz Radecki and the support of the Pharmaceutical Supply Company "CEFARM". The museum is named after Antonina Leśniewska, a pioneer in the field of pharmacy and the first Polish woman to hold a master's degree in pharmacy. Initially, it was located in a tenement house at 72 Marszałkowska Street, where Leśniewska's pharmacy operated. In 1996, it was moved to the headquarters of "CEFARM", and since April 2006, the museum has been housed in a historic tenement at 31/33 Piwna Street, where the architect Tylman van Gameren once lived. The museum collects around 2,500 exhibits related to pharmacy and has an extensive library with 2,600 items. The exhibition is spread across three rooms and includes, among other things, original equipment from interwar pharmacies and pharmaceutical laboratories. Among the more interesting exhibits are pharmaceutical furniture from the turn of the 18th and 19th centuries and an exhibition dedicated to Japanese folk pharmacy. The museum also organizes lectures and educational activities for schools. Thanks to its rich collection, the Museum of Pharmacy not only documents the history of pharmacy in Poland but also contributes to the popularization of knowledge about this field in society.
