The General Land Office (GLO) (1812 - 1946) was an independent agency of the United States government responsible for public domain lands in the United States. Created in 1812, it took over functions previously conducted by the Department of the Treasury. The GLO oversaw the surveying, platting, and sale of public lands in the western United States. It also administered the Preemption Act of 1841, which allowed individuals who were already living on federal land to purchase up to 160 acres of land before it was offered for sale to the general public, if they met certain requirements. Following the passage of the Homestead Act in 1862, which was also administered by the GLO, claims under the Preemption Act sharply decreased. The GLO became a part of the newly-created Department of the Interior in 1849. In 1891 Grover Cleveland and Congress created 17 forest reserves, due to public concern over forest conservation, which were initially managed by the GLO, until they were transferred to the Forest Service in 1905. In 1946 the Government Land Office was merged with the United States Grazing Service to become the Bureau of Land Management. Today the Bureau of Land Management administers the roughly 246 million acres of public land remaining under federal ownership. More by this mapmaker...

John T. Bowen (b. c. 1801 - 1856) was a lithographer active in Philadelphia during the mid-19th century. Born in England, Bowen immigrated to the United States in 1834 and worked as a colorist and lithographer in New York City before moving to Philadelphia in 1838, most like with his collaborator and lithographic artist Alfred Hoffy. Once in Philadelphia, Bowen took over the business of Wild and Chevalier, located at 94 Walnut Street, and began publishing History of the Indian Tribes by McKenney and Hall. He also acquired the rights to Wild and Chevalier's series of views of Philadelphia, which he reissued at the end of 1838 and again in a hand colored edition in 1848. By the early 1840s, Bowen's work was garnering praise, and gained a reputation as one of the best lithographers in Philadelphia. He published the 'Architect's Digest' in 1839 and printed plates for Audubon's Quadrupeds (1845 - 1848) and the octavo edition of Birds of America (1839 - 1844). Despite numerous successes, Bowen field for bankruptcy in 1842, though it did not prove to be too much of a hindrance to his career, as, after 1844, he began working predominantly with Audubon and his sons on their works. Over the course of his career, Bowen became the preeminent Philadelphia lithographer and the most important mid-19th century American publisher of publication plates. By Bowen's death in 1856, he had a fairly substantial estate and a prosperous business. His wife, Lavinia, with whom he had a son, took over the business after her husband's passing and the firm Bowen and Company operated until around 1870. Learn More...
