Gustav Sohon (1825–1903) was an artist, interpreter, and topographical assistant.
Born in 1825 in Tilsit, East Prussia, Gustav Sohon immigrated to the United States in 1842 at the age of 17. In the early 1850s, he enlisted in the U.S. Army. Upon his enlistment he was stationed in the West, and eventually found his way to Fort Steilacoom. One of his first assignments was with Lieutenant John Mullan, who was surveying the country between the Rocky and Bitterroot Mountains for the Pacific Railroad Surveys railroad survey led by Isaac Stevens.
From that moment on, Sohon witnessed and contributed to some of the most momentous events in the history of the Northwest. As an army private, he served with the Stevens railroad survey for over a year before his artistic ability came to the Governor's attention. Sohon proved to have a flair for linguistics, and was soon fluent in the Flathead and Pend d'Oreille languages. This skill enabled him to communicate with the Indians, and allowed him the opportunity to draw portraits of many of the most important Native American leaders. It is because of Sohon's easy way with native conversation that we can now witness his perspective of the past through the expressive images he created.
Sohon was also a talented painter, who produced accurate landscapes and vivid scenes from native life, including the first panoramic view of the Rocky Mountains and the earliest-known sketch of the Great Falls of the Missouri. He also recorded several of the treaty councils during his time with Stevens. Sohon's artistic abilities place him the same league with such other, better-known Western artists as George Catlin, Paul Kane, and Karl Bodmer. As an artist, Sohon was a product of his time and his depictions of treaty events reflect this. His drawings and watercolor paintings allow everyone who views them to see, through his eyes, the treaty councils between the United States Government and Indian tribes of the Pacific Northwest.
