The original line-up consisted of:
Lenz aka Lenz Müller: bass, backing vocals
Fisch aka Martin Fischer (6): drums
Rämi aka Stephan Ramming: vocals, guitar
In 1989, after the release of their album Der Böse Bub Eugen - Himmel, Hölle Und Der Fisch, Lenz left the band. In 1990 they changed their name to just Eugen and reformed with a different line-up. In 1998 they stopped their Eugen project alltogether after their new guitar player left the band to become a fulltime dad.
Lenz and Fisch both now play in a band called “50 Foot Mama” from Zurich. Rämi works as a sports reporter for the newspaper NZZ.
