Nebraska History Spotlight: Cass County Historical Society

A large, weathered wooden shipping crate labeled with destinations including Bremen, New York, Plattsmouth, Nebraska, and Nordamerika, addressed to Christian Gauer.

The Cass County Historical Society Museum at 646 Main in Plattsmouth, tells the county’s history since 1854, the year it was opened for settlement. Permanent displays depict various stages in the county’s history and are supplemented by temporary exhibits that are changed periodically throughout the year. Visitors learn about the golden age of steamboating on the Missouri River, the pioneer experience, the arrival of the railroad, and the importance of farm production. A second part of the permanent display covers the age of the automobile, the telephone and radio, churches and religious life, schools, and entertainment. There is a Pioneer room, a Victorian Parlor, and a General Store.

“The Heights”. Egg tempera painting by John Falter

One of the most interesting items in the collection is a painting by John Falter, who was born in Plattsmouth and became a well-known artist who illustrated covers for The Saturday Evening Post. In 1969, he donated an egg tempera painting of “The Heights,” the home of his grandfather, George E. Dovey.

The Society also maintains the Joseph and Mary Cook log cabin (built in 1868), a Burlington Northern caboose, and a replica of Lewis and Clark’s white pirogue, which sits at Second and Main in Plattsmouth. Located southeast of town is Rock Bluffs School, a one-room brick schoolhouse which was built in 1870 as the “Naomi Institute.”  It is listed on the National Register of Historic Places.

The museum is operated by the Cass County Historical Society, founded in 1936. The present facility was built in 1960, with additions made to the building in 1972, 1980, and 1986. The Davis Conference Room, added in 1986, is used for research, meetings, exhibits, and storage. The Museum has outgrown its building, both in terms of exhibition space and storage space. In 2023, the Board of Directors started a fundraising drive for a new addition. Two buildings in the courtyard that are in poor condition will be demolished, and a new 10,000-square-foot building will include exhibition space and climate-controlled storage. The Board is planning to break ground in 2026, which will also be the 90th anniversary of the Historical Society.

The museum is open year-round, 12:00 pm to 4:00 pm Tuesday through Saturday, and is closed on Sundays, Mondays, and major holidays. Admission is $2.50 for adults. There is no charge for museum members or children. The log cabin, caboose, pirogue, and Rock Bluffs school are open for special events or by appointment. The Museum has two staff members: Margo Prentiss, Curator, and Linda Duncan, Registrar. Many volunteers help throughout the year with maintenance projects, tours, fundraising, and as front desk receptionists. In 2024, the museum had visitors from 23 states and 3 foreign countries (England, Japan and Germany).

About NSHS

The Nebraska State Historical Society was founded in 1878 by citizens who recognized Nebraska was going through great changes and they sought to record the stories of both indigenous and immigrant peoples. It was designated a state institution and began receiving funds from the legislature in 1883. Legislation in 1994 changed NSHS from a state institution to a state agency. The division is headed by Director Daryl Bohac. They are assisted by an administrative staff responsible for financial and personnel functions, museum store services, security, and facilities maintenance for NSHS.
