Born in Geneva, Switzerland, Eduard Louis Berthoud (pronounced "Bare-too") came to the United States with his parents in 1830. His childhood was spent in New York State along the Mohawk River.
After completing a degree in engineering at Union College in Schenectady, he spent a lifetime supporting the great western movement. In 1860, Berthoud came to the Rocky Mountains with the Gold Rush. During the 40 years between 1850-1890, Berthoud contributed greatly to the expanding west through his experiences as a young surveyor on the Panama Railroad, the linking of Leavenworth, KS to the Rocky Mountains, and his survey and exploration of a transcontinental road through Colorado's Middle Park.
As a Coloradoan, Edward Berthoud (his name now "Americanized) also lead surveys for railroads to booming mining camps in Gilpin County, Georgetown, Leadville and San Juan County. Berthoud's legacy includes his pioneer survey of Berthoud Pass and wagon road through Middle Park into Utah. In addition to his work as a surveyor, Berthoud also helped create the School of Mines and often taught there. He also was involved in various political positions from territorial legislator to Golden's Mayor. He collected natural history specimens for eastern museums that even today are considered extremely valuable.
