Portrait of Thomas Zebrowski


Zebrowski studied philosophy and theology at Vilnius University.[1] He briefly taught at Jesuit schools in Kražiai, Ilūkste, and Babruysk and prepared construction projects for churches in these towns. They displayed features of Baroque churches in Vilnius.[3] He also designed the Jesuit school in Zhodishki [be], houses for nobles, and other buildings.[1] Though documentary evidence is lacking, it is suspected that Zebrowski was also involved in construction of churches in Minsk and Płock, as well as the Oginski residence in Ručyca [be] (Hanuta) village.[3]

After studying at Charles University in Prague under Joseph Stepling in 1750–52,[1] Zebrowski returned to Vilnius, becoming a popular lecturer of physics and astronomy at Vilnius University.[4] He was also interested in geodesy, horology, mineralogy, geography.[3] However, his major passion was astronomy and he pursued funding for an observatory. The construction was funded by Elżbieta Ogińska-Puzynina, while Mikolaj Radziwill and bishop Józef Sapieha donated 13.5-centimetre (5.3 in) and 10-centimetre (3.9 in) diameter reflector telescopes manufactured in Germany.[2] Zebrowski designed the observatory; its construction began in 1753.[4]
