context: The school was opened by Empress Maria Fedorovna in Pavlovsk in 1806.

To facilitate the fate of this boy and similar children, Maria Fedorovna instructed her to write out one of the most famous professors from abroad in order to establish a school for the deaf in St. Petersburg. In the same 1806, a priest and professor Wincent-Anselm Zygmunt was discharged from Poland, and he became the first teacher and organizer of educational work in the deaf and dumb school.
