Soon Heine had his own workshop where he manufactured artificial limbs, stretching beds, wheelchairs and other orthopedic appliances and offered them for sale. In 1807 Heine published his Systematic Index of surgery instruments,
bandages and machines, a kind of catalogue for physicians, with later editions in 1811 and 1827. His subsequent publications soon met with recognition among medical experts. He declined an offer to work in Berlin and stayed in Würzburg. The Bavarian crown prince awarded him an order for his merits ("Goldene Zivil-Dienst-Medaille") and even
Johann Wolfgang von Goethe knew Heine's publications and included them in his library. He got to know "Operateur Heine" at the dinner table of
Grand Duke Karl August and invited him to his private home. In 1816 Johann Georg Heine opened the first orthopedic institution on German soil. A former monastery (Stephanskloster) in Würzburg housed it and later it became well-known all over Europe as the
Karolinen-Institut named after Queen Caroline of Bavaria. By that time the successful mechanic had become a physician although he had no classical medical knowledge. When he started to cure non-orthopedic diseases he provoked conflicts with the rest of the Würzburg doctors, which put an end to a long period of successful co-operation. == The dark years ==
