These papers were deposited with the Smithsonian along with manuscripts on botany, which form part of Record Unit 1010014. The present material consists chiefly of
two possibly related series. One is the manuscript for his 1874 privately printed book, The Mechanism of the Universe, which was an attempt to find a coherent scheme
to all motive powers in the universe, from physics to physiology. Included in this record unit are illustrations and an analytical table of contents that were not printed.
The second series consists of notes, arranged by subject, on various aspects of natural science, including meteorology, climatology, geography, zoology, botany, and horticulture.
These materials may have been intended to form the basis of a book, perhaps a companion to Fendler's Mechanism, as none of these topics are dealt with there. This record
unit also includes a covering memorandum to the manuscript, dated June 16, 1900, from Randolph Iltyd Geare, Chief of Correspondence and Documents, to Richard Rathbun, Assistant
Secretary; a letter from Fendler to Engelmann, April 22, 1854, written from Venezuela; and botanical illustrations.
Augustus Fendler (1813-1883), a natural history collector, was born in Prussia and spent one year at the technical school in Berlin. In 1836 he emigrated to Baltimore,
and for the next eight years found irregular employment in trades in Philadelphia, New York, St. Louis, and New Orleans. He tried homesteading in Texas in 1839, and lived
as a hermit on a Missouri River island in the winter of 1841-1842. A trip to Prussia in 1844 and a visit to Ernst Meyer, Professor of Botany at the University at Konigsberg,
awakened him to the commercial possibilities of collecting botanical specimens. At first collecting in the Mississippi River valley, Fendler collaborated with botanist George
Engelmann of St. Louis in identifying specimens. At the outbreak of the Mexican War, through the help of Asa Gray, he was provided with free transportation with United States
troops to Santa Fe, where he collected during the years 1846-1847. Gray's descriptions of these plants are classics in the field, and the Smithsonian purchased a set of his
specimens. In 1849 Fendler attempted an unsuccessful expedition to the Great American Basin. Later collecting trips were to Panama, Arkansas, and Venezuela, where he lived
for five years in the late 1850s. While in Venezuela, Fendler amassed a great collection of flora and became a meteorological correspondent of the Smithsonian. His travels
continued in his later life as well, including Missouri, Prussia, Delaware (where he wrote The Mechanism of the Universe), and Trinidad, where he continued his botanical
collecting until his death.
