The Newens Sanitary Dairy Historic District is located in Des Moines, Iowa, United States.

Newens Sanitary Dairy communicated their intent to produce a fresh, quality safe product.

Adrian Newens, Lynn's brother and company president, had been a professor of oratory at nearby Drake University and Iowa State College before starting a successful speaking career.

The business moved from University Avenue in 1935 and the company made one last name change in the 1940s to the Northland Milk Co.

The dairy complex comprised a front office, milk processing and bottling area, vehicle storage and a stable for the horses.

The two main reasons the milk was processed was to destroy human pathogens through pasteurization and to maintain product quality.

Newens advertised, “Pasteurized Milk and Cream, Buttermilk and Cottage Cheese" and "You are invited to inspect our plant at any time.

They utilized the former dairy processing area and vehicle storage building, and rented the storefronts and offices to various tenants over the years.

Lynn Newens and his wife Susan, who worked as the company's bookkeeper, and their daughter moved into a house to the east of the dairy at 2220 University Avenue around 1913.
