Butterworth Station, built in 1820 as the home of Benjamin and Rachael Moorman Butterworth, was the southernmost station on the Underground Railroad in Warren County. Quakers and abolitionists who opposed slavery in Virginia, they bought 1,500 acres along the Little Miami River and moved to Ohio in 1812. Until nearly 1850, the family fed and sheltered large numbers of runaway slaves at great personal risk before transporting them to the next station. After the Little Miami Railroad was built in the 1840s, Henry Thomas Butterworth donated land and water and helped with construction, and the railroad established a stop called Butterworth Station, granted his family lifetime passes, and built on this site a water tower with a passenger waiting area that served for decades as a railroad water station. The family also made important educational and civic contributions: William Butterworth, son of Benjamin and Rachael, planned the Maineville Academy, a private school of higher learning in Maineville that opened in 1848 in a two-story brick building with Professor John W.B. Foster as headmaster and a boardwalk from Foster to the academy for students arriving by train. Among those associated with the family, Clarkson, son of Moorman Butterworth, became a skilled mathematician, writer, and historian; William's son Benjamin served as a five-term Congressman and U.S. Director of Patents; and Benjamin's son William married Katherine Deere, granddaughter of John Deere, and as president of Deere & Company introduced the company's first line of tractors. In 1930, William and Katherine donated 150 acres to the Girl Scouts to establish Camp Butterworth.
