Emil Baumgartner is shown making cheese during the 1923 Cheese Day celebration, which came after a five-year break in the festival. He and his equipment were seen on the decorated truck sponsored by Wisconsin Sharples Company - J. Zurbachen & Company, a cheese and cheese equipment dealer. The Sharples separators, manufactured from the 1890s to the 1930s, were originally manufactured in West Chester, Chester County, Pennsylvania and were the first American invented cream separators. The photograph was donated to the National Historic Cheesemaking Center by Lyle Baumgartner.
