The term morbus haemorrhagicus maculosus entered the medical lexicon in 1735, courtesy of the German physician Paul Gottlieb Werlhof. While he later saw his work linked to idiopathic thrombocytopenic purpura, his primary records remain a testament to eighteenth-century clinical observation and the rigorous classification of bleeding disorders during an era of significant medical transition in Europe.
Early Education and Clinical Practice
Born in 1699 in Helmstedt, Germany, Werlhof pursued his medical training at the University of Helmstedt. Under the instruction of Lorenz Heister and Brandanus Meibom, he established a foundation in both clinical medicine and the academic study of disease. Following the completion of his studies, he spent four years practicing in Peine before relocating to Hanover in 1725, where he began to establish a professional reputation that would eventually span the continent.

Werlhof achieved significant professional standing in 1740 when he was appointed Königlicher Leibarzt, serving as physician to the Hanover royalty. His influence extended through his membership in elite organizations, including the Royal Society, the German Academy of Sciences Leopoldina, and the Göttingen Academy of Sciences and Humanities in Lower Saxony. His status was further cemented by his appointment as a Fellow of the Royal Society, acknowledging his contributions to the medical field.
Medical and Literary Output
Werlhof maintained a distinct separation between his professional writing and his creative interests. He published his medical treatises in Latin, most notably the 1732 work Observationes de febribus. Conversely, he expressed his artistic side by composing poetry and hymns in German, collecting his verse in the volume Gedichte. His intellectual circles included the anatomist Albrecht von Haller, with whom he shared a mutual interest in poetic composition.
Death and Legacy
Werlhof remained active in Hanover until his death in 1767. He was buried at the Alter St.-Nikolai-Friedhof. His clinical description of haemorrhagic conditions provided a window into the diagnostic limitations and observations of his time, as modern analysis suggests his 1735 case report of a ten-year-old patient likely described a generalized coagulation disorder rather than idiopathic thrombocytopenic purpura.
