Marcin Knackfus

[1] His date of birth is not known but is estimated based on the assumption that he was around 25 years old in 1767 when his first child was born and when he joined the Grand Ducal Lithuanian Army as construction engineer.

[4] Knackfus studied architecture in Warsaw and was influenced by other local architects of late Baroque (Ephraim Schröger and Szymon Bogumił Zug) and early Neoclassicism (Domenico Merlini and Johann Christian Kammsetzer).

[5][6] Knackfus taught at the Lithuanian Engineering Corps military school from 1769 until 1773[1] before becoming the first professor of architecture at Vilnius University until 1777.

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.
