George Engelmann

thumb|George Engelmann George Engelmann, aka Georg Engelmann, (2 February 1809 – 4 February 1884) was a German-born, American physician and botanist, known for his pioneering research in the Rocky Mountains and northern Mexico. In 1863 he became a Member of the U.S. National Academy of Sciences. Quotes The only Cactus known to Linnæus from the countries north of Mexico was his Cactus#Taxonomy Cactus Opuntia (Opuntia vulgaris). Long after him, more than forty years ago, Thomas Nuttall Nuttall, the pioneer of West American botany, discovered two Mammillaria Mamillariæ and two Opuntia Opuntia on the upper Missouri, and again, twenty years later, in California, a new Echinocactus.

Metcalf was active in publishing during the 1840s and 1850s and was the younger brother of Eliab W. Metcalf, who died in 1835.) The species of our Junipers, are, on the whole, well enough recognized, but their scientific definition is very insufficient—the characters, given in the books, vague and indefinite.I have had a good opportunity to study the different species and forms from all parts of our country, fresh and living as well preserved in numerous collections; among them those contained in the great Herbarium#Institutional herbaria Herbaria of New York and Cambridge, Massachusetts Cambridge (John Torrey Torrey and Gray) and those of Kew Gardens Kew (Joseph Dalton Hooker Hooker), and especially those of Berlin, whence the types of the different Mexican species were sent to me by my late excellent friend, Alexander Braun.With the exception of Juniperus sabina Junipera Sabina, which with us is always a prostrate plant, all our species occur both in the form of low shrubs or of trees, a few of them of magnificent dimensions. In the arid mountain regions, the trunks of the different species which occur there frequently assume peculiar conical forms, very thick at base and rapidly tapering to a slender point. 1877 The American junipers of the section Sabina Transactions of the Academy o Science of St. Louis III 4 https://books.google.com/books?id=8BlN-tVZb4kC&pg=PA583 583–592 (quote from p. 583; offprint by R.P. Studley, printers) Quotes about George Engelmann Dr. Engelmann received his medical education and early scientific training at Berlin, Heidelberg and Frankfurt-am-Main Frankfurt. Agassiz, Alexander Braun, and Karl Friedrich Schimper Charles Schimper were among his college-associates and lifelong friends. He left Germany almost at once after his graduation, reaching New York in 1832. His first visit was to Philadelphia, where he was fortunate enough to make the acquaintance of Thomas Nuttall Nuttall and other scientific men. ...... From 1835 until his death Dr. Engelmann continued to live in St. Louis and to devote to scientific investigations every moment which could be spared from a large and absorbing professional practice.
