Thomas Gamaliel Bradford (1802 - 1887) was born in Boston, Massachusetts, where he worked as an assistant editor for the Encyclopedia Americana. Bradford's first major cartographic work was his revision and subsequent republishing of an important French geography by Adrian Balbi, Abrege de Geographie published in America as Atlas Designed to Illustrate the Abridgment of Universal Geography, Modern and Ancient. Afterwards Bradford revised and expanded this work into his own important contributions to American cartography, the 1838 An Illustrated Atlas Geographical, Statistical and Historical of the United States and Adjacent Countries. Bradford's cartographic work is significant as among the first to record Texas as an independent nation. In his long career as a map publisher Bradford worked with William Davis Ticknor of Boston, Freeman Hunt of New York, Charles De Silver of Philadelphia, John Hinton, George Washington Boynton, and others. We have been able to discover little of Bradford's personal life.
