Samuel C Mills (1833–1911) was a Washington, D.C.-born photographer who documented James H. Simpson’s 1858–1859 expedition across the Great Basin, including White Pine County, Nevada, capturing some of the earliest photographs of the Oregon and California Trails and Native American subjects, before transitioning to a career as a police judge and temperance advocate.

Early Life and Beginnings in Photography (1833–1856)
Samuel C Mills was born on October 8, 1833, in Washington, D.C., to John and Mary Mills. Growing up in the capital, he worked in his father’s shoe factory as a young man, gaining practical experience but showing early interest in the emerging field of photography. In 1856, at age 23, Mills joined the photography studio of Blanchard P. Paige on Pennsylvania Avenue, where he honed his skills in portraiture and wet-plate collodion photography, a complex process requiring glass negatives and immediate development.
Expedition with James H. Simpson (1858–1859)

Mills’ most notable contribution came during his role as expedition photographer for Captain James H. Simpson’s 1858–1859 survey of the Central Route across the Great Basin, including White Pine County, Nevada (as referenced in prior conversation). Hired in March 1858 at $40 per month, with Edward Jagiello as his assistant at $25 per month, Mills was tasked with documenting the expedition’s journey from Fort Leavenworth, Kansas, to Camp Floyd, Utah, to map a wagon road for military and emigrant use during the Utah War.
The expedition departed on May 31, 1858, after Mills and Jagiello tested their equipment at Fort Leavenworth, producing early views of an artillery battery and three surviving photographs of the fort’s buildings. Simpson instructed Mills to capture “as many prominent scenes as possible,” including Fort Kearney, Court House Rock, Chimney Rock, Fort Laramie, and Ash Hollow, emphasizing topographical and geological features for the expedition’s report. On July 25, 1858, a team member noted Mills photographing Court House Rock, highlighting his active role.
At Camp Floyd, Mills and Jagiello set up a makeshift darkroom, producing paper prints from glass negatives, including views of the sprawling military garrison, then the largest in the U.S. Mills also photographed a Ute delegation led by Chief Arapeen on January 20–21, 1859, capturing a group portrait and a solo image of Arapeen, some of the earliest photographic records of Native Americans in the region. However, Simpson grew frustrated with Mills’ drinking habits, which impaired his duties. After multiple warnings, Simpson dismissed Mills on January 19, 1859, but reinstated him with a stern admonition following Mills’ plea for another chance. Concerns over dwindling photographic chemicals further limited Mills’ output.
The expedition returned to Washington, D.C., in September 1859, with no known photographs from the return journey, suggesting the camera was packed away. The delicate glass negatives were likely delivered to the War Department, though their ultimate fate is unknown. Mills’ employment ended upon the expedition’s conclusion, leaving behind the earliest surviving photographic record of the Oregon and California Trails.
Civil War and Transition to Law (1860–1872)
Returning to Washington, Mills resumed work at Paige’s studio, photographing soldiers as the Civil War began in 1861. In 1864, he enlisted in the Union Army as a hospital steward, serving until the war’s end in 1865. After the war, Mills returned to photography but began studying law, passing the bar in 1872. His legal career soon overshadowed his photographic work, marking a shift from his earlier artistic pursuits.
Later Life and Civic Engagement (1872–1911)
In 1872, Mills was appointed a police judge in Washington, D.C., a position he held for the rest of his career. His experiences with alcohol during the Simpson expedition may have influenced his commitment to temperance, leading him to found the Sons of Jonadab, a temperance organization. Mills was also an active member of the Grand Army of the Republic, a Union veterans’ group, and the Masonic Order, reflecting his civic engagement. He died on October 7, 1911, and was buried in Congressional Cemetery in Washington, D.C.
Legacy
Samuel C Mills is best remembered for his 1858–1859 photographs, which provide a rare visual record of the Oregon and California Trails and early Great Basin exploration. His work with Simpson’s expedition, despite challenges with alcohol and limited supplies, captured key landmarks and Native American subjects, contributing to the historical documentation of White Pine County and the broader American West. While his later career in law overshadowed his photography, Mills’ images remain a valuable resource for historians studying 19th-century exploration and frontier life.
