Frederick Pursh was born in Siberia, in 1774. Coming to the United States at the age of twenty-five, he spent twelve years in botanical studies, the results of which were published in England under the title Flora Americae Septentrionalis, or a Systematic Arrangement and Description of the Plants of North America (London, 2 vols., 1814). Pursh died at Montreal in 1820, while preparing a flora of Canada.

Aimé Bonpland (1773-1858) was a French scientist and traveller. It has been said that the expedition of Humboldt and Bonpland in tropical America (1799-1804) "laid the foundation of the sciences of physical geography and meteorology in their larger bearings." The fruit of their joint labors appeared at Paris in 1807, under the title Voyage aux régions équinoxiales du nouveau continent.—Ed.
