Heinrich Hoffmann (June 13, 1809 – September 20, 1894) was a German psychiatrist, who also wrote some short works including Der Struwwelpeter, an illustrated book portraying children misbehaving. Hoffmann was born in Frankfurt on Main to an architect father, de, who was responsible for the city's streets and waterways. Hoffmann's mother died when he was a baby. His father later married his mother's sister, Antoinette Lausberg, who was a loving and more than adequate mother to him. Lazy and easily distracted, Hoffmann at first struggled at school, but became a successful student after conforming to the strict discipline imposed by his demanding father. At university in Heidelberg, he immersed himself into the corps student culture. His zest for dueling was small, but owing to his sociability, good humour and wit, Hoffmann soon became the center of many social circles, a pattern that would later repeat itself in his hometown. His progress in his medical studies was slow because of the many distractions. To flee these, he left Heidelberg for Halle, where he concentrated on his studies under Professor Peter Krukenberg, the founder of a charity clinic. His first brush with medical practice coincided with a cholera outbreak in Halle. After getting his medical degree, he intended to spend a year in Paris (funded by the Frankfurt Bethmann Bank) to improve his knowledge of surgery. Due to the deteriorating health of his father, he had to return home early. Hoffmann married Therese Donner and had three children by her, two of whom survived him, as did his wife. He was known to draw comic sketches for his children as well as for his wife. Karl Hessenberg, the mathematician, was his great-grandson. Hoffmann worked for a pauper's clinic and had a private practice. He also taught anatomy at the Senckenberg Foundation. None of this paid very well, and when the Frankfurt lunatic asylum's previous doctor (who was a friend of his) retired in 1851, he was eager to take the post even though he had no expertise in psychiatry.
