Harry King (18xx - 19xx) was an American draftsman. King worked as Chief of the Draftsmen's Division of the General Land Office from at least 1895 and is credited with supervising the creation of numerous maps during his tenure. He was fired (or as it was put in one newspaper 'bounced to the exterior') by the Secretary of the Interior in January 1903 for corruption (he was making maps for individuals outside the Land Office during office hours and getting paid for it) and reportedly asking a female employee questions unrelated to her work (likely 1902 - 1903 newspaper speak for sexual harassment). King denied all the charges against him. We have been unable to locate any other information concerning King or his career. Learn More...

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. Learn More...

Andrew B. Graham (1845 - September 9, 1909) was an American lithographer active in Washington, D.C. in late 19th and early 20th century. Graham was born in Washington D.C., the son of a lithographer and engraver. After college, he joined the U.S. Coast Survey, where he was a draftsman until 1889. He retired from the Coast Survey to take over management of his father's lithography firm. The firm, Andrew B. Graham Company, was one of several that thrived on lucrative government publication contracts. Graham died of 'brain fever' in his Washington D. C. residence on September 9 of 1909. Some of his work was republished posthumously until about 1917, and his firm was active until at least the early 1920s. Learn More...
