1757 Desilver Pocket Map of the United States

Charles Desilver (fl. c. 1850 - 1862) is a little known American map published active in the middle part of the 19th century. Desilver began is cartographic career as a partner in the Thomas Cowperthwait Company, the publisher of S. A. Mitchell popular New Universal Atlas. In 1856 Desilver acquired Mitchell's copyrights and print plates and began to issue his own variant of the New Universal Atlas. Desilver altered Mitchell's maps only slightly; adding a new grillwork border, his own color scheme, new titles, and some updated political data. Despite a noble pedigree, Desilver's maps did not sell well - possibly because they followed the long and very popular run of Mitchell's own atlases. Desliver continued to publish his atlas until 1859 (though we have heard that he also published an 1862 edition). In 1859 he resold the Mitchell copyrights and printing plates to S. A. Mitchell's son S. A. Mitchell Jr. The younger Mitchell again updated the plates with own border and color scheme and began publishing his own successful atlas in 1860.

Samuel Augustus Mitchell (March 20, 1792 - December 20, 1868) Senior began his map publishing career in the early 1830s. Having worked as a school teacher, Mitchell was frustrated with the low quality and inaccuracy of school texts of the period. His first maps were an attempt to rectify this problem. In the next 20 years Mitchell would become the most prominent American map publisher of the mid-19th century. Mitchell worked with prominent engravers J. H. Young, H. S. Tanner, and H. N. Burroughs before attaining the full copyright on his maps in 1847. In 1849 Mitchell teamed up with printer Cowperthwait & Company to produce the Mitchell's Universal Atlas and the Mitchell's General Atlas. In the late 1850s most of the Mitchell copyrights were bought by Desilver and Co. who continued to publish his maps, many with modified borders and color schemes, until Mitchell's son, Samuel Augustus Mitchell Junior, entered the picture. S.A. Mitchell Jr. purchased most of the copyrights back from Desilver and, from 1860 on, published his own New General Atlas. The younger Mitchell became as prominent as his father and published atlases well into the late 1880s when most of the copyrights were again sold and the Mitchell firm closed its doors for the final time.
