History
Eureka is situated on the south bank of the Fox River. Lester Rounds moved his stock of goods from Waukau to the site of Eureka in 1850, where he was joined by Walton C. Dickerson, who moved from Nepeuskun. They became the first settlers and founders of Eureka, a plot of which was recorded on 24 July 1850, of which Rounds, Dickerson and Starr were proprietors. A ferry was established across the Fox River at this point, during the same season, and four years later a bridge was constructed. The post office was authorized on 16 July 1850 and Lester Rounds was appointed postmaster. A steamboat landing and warehouse was built by Dickerson for the accommodation of the daily line of steamboats on the river, running between Oshkosh and Berlin. The sawmills along the river at Eureka, Delhi, Omro and Berlin were supplied with pine logs from the Wolf River, which were towed up the Fox River at first by horsepower boats or tugs.

Twenty-seven-year-old E. R. Jaeger, from Eureka, Wisconsin, followed his brother west to Tacoma, Washington, at the end of the 19th century, where he worked in his brother's laundry. In fall 1894, he decided to go out on his own, to either Alaska or Hawaii. He tossed a coin and Alaska won. The Alaska Laundry Co. continues in the family in Juneau. Jaeger's coin flip left the field open for Servco Pacific, a diversified company founded in 1919, to become the oldest family business in Hawaii.

Argalus J. and Augustus I. Foote constructed the Foote Mansion in Eureka. It had 30 rooms. The floor plan was of two mirrored sets of 15 rooms with a great hall in the center. Local folklore claims the Foote Mansion is haunted and that Al Capone used it as a whiskey distillery during prohibition.
