From March 21, 1912 until his retirement on October 15, 1941, Zangger was professor ordinarius and director of the newly founded Institute for Forensic Medicine.

[2] In 1905 Zangger won international fame as a hero for his role in guiding the rescue in the commune Courrières of over 100 French coal miners trapped underground by an explosion.

The book gave valuable guidelines for combating such dangers and for diagnosing the symptoms caused by the new forms of poisoning and thus for improving therapy and prevention.
