History

Nemaha County was established in 1855 and named after the Nemaha River, which flows through the region and provided early settlers with fertile bottomlands and transportation routes. Brownville, founded in 1854, became one of Nebraska’s earliest cultural and commercial centers, serving as a major Missouri River port and even hosting the state’s first legislature sessions. Auburn, formed from the merger of Sheridan and Calvert in 1882, became the county seat and grew into a regional hub for education, commerce, and civic life. Johnson, Peru, and other small towns developed as agricultural and rail‑supported communities.

The county’s history reflects frontier settlement, river commerce, early statehood politics, and the growth of rural communities anchored by agriculture and education.

Nemaha County at a Glance

Nemaha County, Nebraska — founded in 1855 out of what had been Forney County, and named for the Nemaha River, which took its own name from the Half-Breed Reservation set aside in 1830 for the children of traders and Native women. County seat Auburn exists because two towns, Calvert and Sheridan, merged in 1882 expressly to assemble the votes to take the seat from Brownville, ten miles east — and did, in 1883. (Some sources say 1885; that is probably when the records physically moved.) At 410 square miles Nemaha is one of Nebraska’s smallest counties. Population peaked at 14,952 in 1900 and is near 7,050 today, less than half its height. 29 listings across 9 towns.

Getting there: US-75 runs north and south, US-136 crosses east and west through Auburn as Central Avenue, plus NE-62, 67 and 105. BNSF freight; the abandoned Missouri Pacific river line is now the Steamboat Trace Trail. The Missouri River forms the eastern boundary — and McKissick Island, stranded east of the channel and physically attached to Missouri, is still legally Nebraska. Central Time.

Brownville was once the largest settlement in Nebraska Territory, a Missouri River port of 1,309 people in 1880. A failed railroad venture left the town servicing bond debt while the railroads elsewhere killed the river-freight trade that had made it. Population today: 142. What survives is remarkable for a village that size — a Nebraska Arts Council certified Creative District, with the Brownville Village Theatre, the Brownville Concert Series, the Lyceum bookstore, galleries and wineries. Berthed on dry land is the Captain Meriwether Lewis, the steam paddle dredge launched in December 1931 that cut the Missouri navigation channel for the Corps of Engineers until 1976 — 269 feet long, 25-foot paddlewheels, a National Historic Landmark since 1989, and since 1981 the home of the Museum of Missouri River History.

Peru State College, eleven miles northeast of Auburn, is Nebraska’s first and oldest institution of higher education — incorporated as Mount Vernon School in December 1865, opened in 1866, and a state normal school from 20 June 1867, with first classes that October. Near Brownville, Cooper Nuclear Station is the largest single-unit generator in Nebraska at 835 megawatts net, in commercial operation since July 1974, named for Guy Cooper Sr. and Guy Cooper Jr. of Humboldt, who between them gave 27 years to the NPPD board.

For visitors: Indian Cave State Park straddles the Nemaha–Richardson county line in the roughest, most heavily timbered country in eastern Nebraska — 3,052 acres, 22 miles of hike-and-bike and 16 miles of equestrian trail, Ash Grove and Hackberry Hollow campgrounds with showers and dump stations, a Missouri River boat ramp, disc golf, and the partly rebuilt ghost town of St. Deroin, the county’s first settlement. The sandstone cave carries petroglyphs of undetermined age. The Steamboat Trace Trail runs 22 crushed-limestone miles from south of Nebraska City to just below Brownville, with trailheads at Brownville and Peru — and it closes each year for the November and January rifle deer seasons, which is the detail most travel guides leave out.

The first claim under the Homestead Act was filed at the Brownville land office on 1 January 1863 — the first day the Act took effect, one of 417 applications lodged nationwide that day, and for land in Gage County. Nemaha’s claim is the land office, not the homestead. The Nebraska State Fair came to Brownville in 1870 and 1871.

Born here. Eugene Allen Gilmore (Brownville, 4 July 1871), Vice Governor-General of the Philippines 1922–29, twice acting Governor-General, and President of the University of Iowa 1934–1940. Elzada Clover (Auburn, 1897), the botanist who with Lois Jotter ran the Green River and Grand Canyon in 1938 — 600 miles in 43 days, and the first two women to do it.
