Henry Schenck Tanner

Henry Schenck Tanner (c. 1786–1858), was an American cartographer, born in New York City.

Tanner wished to provide a geographic account of the spread of the disease, stating that other statistics concerning the epidemic were "given in such a loose and unconnected manner as to render a reference to them at once irksome and unprofitable."

His publication included global, national and local maps, data tables showing number of deaths in different localities by country, and detailed maps of the United States and New York City with small red dots indicating points where the disease had broken out.

Tanner and his colleague John Vallance engraved the maps of the United States that were produced between 1816 and 1823 by geographer John Melish in Philadelphia and that were among the first widely spread US maps to include the West Coast territories then belonging to Mexico.

For Stephen F. Austin, Tanner engraved and published a map of Texas in 1830 which was widely distributed.
