James Webster (fl. early 19th century) James Webster (fl. early 19th Century) was a Philadelphia and New York based publisher active in the first half of the 19th century. Little is recorded of Webster's life beyond his publication of several maps in the 1830s. Webster's most significant work seems to have been his rare 1835-1836 Map of the United States, which seems to have been borrowed whole or in part from other prominent cartographers of the period including Phelps and Mitchell.
