Wizli Wisso

Wizli Wisso (died 1350) was a knight of a Zurich ministerial family; his grandfather had died fighting for Habsburg at the Battle of Morgarten in 1315. After Rudolf Brun's guild revolution of 1336, Wizli joined the patrician exiles who sheltered in Rapperswil.

On the night of 23–24 February 1350 he took part in their attempt to seize Zurich and overthrow Brun, later called the Murder Night of Zurich. The coup failed and Wizli was killed in the fighting; Brun confiscated his estates.
