About the Author: Heinrich Hoffmann

Note: There is more than one Heinrich Hoffman.

Heinrich Hoffmann was a German psychiatrist, who also wrote some short works including Der Struwwelpeter (German for either "slovenly Peter" or "shock-haired Peter"), an illustrated book portraying children misbehaving.

He wrote under the following names:

- Polykarpus Gastfenger (The given name is the German version of that of a Christian martyr; the surname sounds like "Gastfänger", which could be a common noun for "guest-catcher".)
- Heulalius von Heulenburg
- Heinrich Hoffmann
- Heinrich Hoffmann-Donner (The second half of the compound surname would mean "thunder" as a common noun, or a name for the Germanic thunder-god Thor.)
- Heinrich Kinderlieb (The surname means roughly "love of children")
- Reimerich Kinderlieb
- Peter Struwwel (This name reverses the order of the components of "Struwwelpeter".)
- Zwiebel (As a common noun, this would mean "onion")

In Frankfurt/Germany there is a Heinrich-Hoffmann-Museum Frankfurt.

Hoffmann studied medicine in Heidelberg. From 1851, he was director of the municipal psychiatry in Frankfurt.

He is the subject of the historical novel, 98 Reasons for Being.
