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 firm Thomas, Cowperthwait and 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.
