This reminds me of Pjotr Kraska, better known as 'the King of Zurich' (who died in 2016).

Unfortunately I can't find anything about him in English, but here's a link in German:

A really interesting fellow. Obviously had some mental health issues but was tolerated (surprisingly and warmly by Swiss standards) by the public and officials.
