Georg Heinrich Wilhelm Schimper was a German botanist and naturalist born in Reichenschwand.
Wilhelm Schimper studied natural history in Munich, and for a short period of time worked with geologist Louis Agassiz as a draftsman and illustrator.
He was a brother to naturalist Karl Friedrich Schimper. In 1831 he undertook a botanical collection trip to Algiers, about which, he published Reise nach Algier in den jahren 1831 und 1832. A few years later he conducted botanical research in Egypt and the Sinai, eventually settling in Ethiopia in 1836.
During his time spent in Ethiopia he had residences in Tigray and Semien provinces. Although he was imprisoned at Magdala by Emperor Tewodros II, otherwise he suffered no serious losses during that unsettled time. While in Ethiopia, he maintained correspondence with botanists in Europe, and made valuable contributions to natural history collections in Paris and Berlin, and was a collector for Unio Itineraria in Württemberg.
During the years 1864 to 1868 he wrote an extensive report on his observations made in the course of his botanical trips through Tigray in northern Ethiopia. The manuscripts came to the British Museum in 1870 and are now kept in the British Library. They are available online in the public domain.
Schimper died in Adwa. His name is commemorated by the botanical genera Schimpera, Schimperella and Schimperina. The species epithet schimperiana is attached to a number of plants.
A few examples being Habenaria schimperiana, Pyrrosia schimperiana, Festuca schimperiana and Kalanchoe schimperiana.
