In 1804, in Warsaw, a humanistic secondary school for boys was opened, divided according to the Prussian educational model into six classes, plus two preparatory ones.
The Evangelical-Augsburg Lutheran from Thorn in Royal Prussia had studied theology and philology at the University of Leipzig and had taught the Polish language there.
The school was initially located in the leased north wing of the Saxon Palace, named after and owned by the German House of Wettin.
Two Wettin Electors of Saxony had been kings of Poland between 1697 and 1763, and a third Saxon ruled the Duchy of Warsaw from 1807 until Napoleon's defeat in 1814.
[4] Samuel Linde remained the Lyceum's director when the city, in 1815, came under Russian control as part of the Kingdom of Poland.
