       The proposal to award Johann Hoschek with honorary citizenship of Cieszyn was lodged by Dr Rudolf Bukowski at a meeting of the Town Council of 16 February 1898. Along with Hoschek, the names of four other individuals were put forward, and all of these men shared many years of dedicated work as members of the town’s local authority. Many people took part in the discussion but the proposal was passed unanimously.
