Stryj (now Stryi)
The secondary school that Józef Koffler attended was founded in 1873 as the highest-level Realschule in the Austro-Hungarian educational system and transformed into a gymnasium (secondary school) ‘with obligatory drawing classes’ in 1880. The school building was situated in Tadeusza Kościuszki Street (renamed as Józefa Piłsudskiego Street in 1935).
