Koch House & Dairy Legacy

The Koch House: From Family Farm to Community Landmark

The Koch House, now preserved at Old Falls Village Park, represents a rich chapter in Menomonee Falls history—one that blends family legacy, local industry, and community life.

Originally built in 1873, the home was purchased by Margaret Koch, who later played a key role in ensuring its legacy. Upon her death in 1913, she willed the house and surrounding land to the Women’s Club of St. Paul’s United Church of Christ in exchange for perpetual care of her family’s gravesite. That gravesite still exists today, a quiet reminder of the family’s early roots in the area.

The Beginning of Koch’s Dairy

In 1920, Margaret’s great nephew, William “Billy” Koch, purchased the property from the church and launched Koch’s Dairy. At age 40, William made a significant career change after spending 15 years as a local mail carrier, choosing instead to build a business that would become a staple of the community.

From the beginning, Koch’s Dairy focused on quality and service. In its first year, William installed a large Kelvinator refrigerator—an advanced feature for the time—demonstrating his commitment to providing the best possible service to his customers.

A True Family Operation

By 1930, Koch’s Dairy had become a fully integrated family business. Every member of the household contributed:

  • Meta Koch managed sanitation and mechanical operations

  • Harold oversaw the storeroom and electrical systems

  • Arthur assisted with milk sales and deliveries

  • Daughter Meta handled bookkeeping and cashier duties

  • Lucille prepared meals for workers

The dairy was self-sufficient, raising its own cows for milk production. These cows grazed along the shaded side of the property, giving rise to the name “Shady Lane,” which remains part of Menomonee Falls today.

From Horse-Drawn Delivery to Modernization

In addition to dairy operations, William raised Percheron horses, which were used to deliver milk throughout the community. This method continued until 1941, when he introduced a delivery truck—modernizing the business while still maintaining some traditional practices.

Customers quickly embraced the truck deliveries, appreciating the cleaner and more efficient service compared to horse-drawn wagons.

Changing Times and the End of an Era

William operated Koch’s Dairy until 1950, when new pasteurization regulations reshaped the dairy industry. At that point, he retired, and his son Arthur continued the business for another decade before selling it to Etzel Dairy. In a reflection of the times, customer accounts were transferred at a rate of 50 cents per household.

A Life of Service

William August Koch was more than a businessman. Born in 1879 to German immigrant parents, he spent over four decades in Menomonee Falls raising his family and contributing to civic life. He served on the Village Council and the County Board of Supervisors, earning a reputation for reliability and dedication.

Whether delivering mail or milk, William was known for his punctuality—even in difficult weather—and for the friendly, cheerful attitude that made him a familiar and trusted figure in the community.

Preservation and Relocation

After William’s passing in 1945, the family continued to live in the home until 1948. The original farm site eventually gave way to development, including the construction of a new post office in 1962.

Recognizing the historical importance of the home, it was donated in 1979 and relocated to Old Falls Village Park. The Village of Menomonee Falls funded the move, while the Menomonee Falls Historical Society undertook the restoration.

A Lasting Legacy

Today, the Koch House stands not only as a preserved structure but as a symbol of a time when local farms, family businesses, and community ties defined everyday life.

Through its story, visitors gain insight into the evolution of agriculture, the impact of industrial change, and the enduring importance of family and service in shaping the history of Menomonee Falls.
