Augustus Koch (1840-?) was one of the most prolific American engravers of Birds Eye Views working outside of the major publishing centers. Koch initially served in the Union Army during the Civil War as a clerk and draughtsman in the Engineers Office in St. Louis. Although his English was poor, he was later commissioned as an officer and assigned to one of the Black regiments serving in Mississippi where he drew maps for the advancing Union forces. By 1865 he is thought to have contracted malaria and at 25, was discharged from the army.
By 1868, Koch had become an itinerant Bird's Eye View engraver. His earliest views are date views of Cedar Falls, Vinton, and Waterloo, Iowa. At that point his career seemed to take off and in rapid succession, maps by Koch were produced in every section of the country. In 1870 he produced 5 maps in Utah, Wyoming and California. In all, Koch produced over 100 views, including over 20 Texas Views, during a career of 30 years. His last recorded view was produced in Montana in 1898.
Reps notes that while Koch engraved fewer views than some of his contemporaries, "no American viewmaker traveled more widely in search of subjects. . . "
