Georg Heinrich Wilhelm Schimper, in Amharic sources known as Sambar (2 August 1804 – October 1878), was a German botanist and naturalist who spent more than forty years in Ethiopia collecting specimens of plants, mainly in Semien, the Tekeze area and around Adwa. Schimper discovered more new African plant species than possibly any other botanist, and numerous plant species bear the epithet Schimperi/Schimperiana.
Wilhelm Philippe Schimper (January 12, 1808 – March 20, 1880, in Lichtenberg) was an Alsatian botanist with French, later German citizenship. He was born in Dossenheim-sur-Zinsel, but spent his youth in Offwiller, a village at the foot of the Vosges mountain range in Alsace. He was the father of botanist Andreas Franz Wilhelm Schimper (1856–1901), and a cousin to naturalist Karl Friedrich Schimper (1803–1867) and botanist Georg Heinrich Wilhelm Schimper (1804–1878).
