Marcin Knackfus

Marcin Knackfus was born in Wólka Ostrożeńska, Kingdom of Poland, near the city of Garwolin. In 1773, Knackfus became an architect of the Commission of National Education and prepared projects for schools. From 1788 on, Knackfus mostly designed reconstruction projects for the city of Vilnius as well as residences for Lithuanian nobles. These include the homes of Heinrich de Reuss LXIII, the Łopaciński family, Andrzej Abramowicz, and Antoni Tyzenhaus. Knackfus worked with numerous nobles, including Vilnius bishops Ignacy Jakub Massalski and Ignacy Krasicki, Field Hetman Ludwik Tyszkiewicz, voivode Karol Stanisław Radziwiłł, Adam Kazimierz Czartoryski, and Grand Marshal Stanisław Lubomirski. == Personal life ==

Knackfus married Agnieszka Pawłowska in 1767. They had two children, Joachim and Katarzyna. Knackfus was a freemason and was a member of three Masonic lodges in Vilnius. Through his masonic connections, he became a supporter of Tadeusz Kościuszko and the 1794 Kościuszko Uprising. Upon the failure of the uprising, Russian forces stormed Vilnius and burnt down many buildings in the Sereikiškės area of Vilnius where Knackfus lived. Fearing retribution for his involvement, Knackfus moved to the Suwałki Region on the Lithuania–Poland border. He died in Vilnius . == Works ==
