Albrecht von Haller (1708-1777) was a famous Swiss anatomist and botanist who studied with Boerhave in Leiden (1725-1727). He was amongst the first botanists who realized the importance of Herbaria in studying the variations in plants. See Stafleu and Cowan, vol. 2, pp. 24-25. A nice, engraved portrait including a large, printed text in Latin, signed by the medical doctor and poet Paul Gottlieb Werlhof (1699-1767), a friend of von Haller. Werlhof is best known for being the first physician to describe thrombocytopenic purpura. The artist is unknown. A bit soiled in the margins, otherwise a very good, clean copy with a strong imprint.
