Rudolf Kern was an important designer and builder in Bydgoszcz, at the end of the Prussian period of the city.

Rudolf Kern allegedly practised in the studio of Józef Święcicki.

At that time, like many architects from Bydgoszcz, he was involved in the design and construction of tenement houses that were then sold to profitable real estate brokers.

[1] In Bydgoszcz, he lived until 1922 in his own house at the corner of Gdańska Street and Adam Mickiewicz Alley[2] Rudolf Kern's style is characterized by Art Nouveau features and details.

In 1912, one of his projects was awarded most beautiful new building of the year (together with Fritz Weidner's house at Kołłątaja street 1), in a competition organized by city authorities: it stands at 20 January 1920 Street 24.
