Campbell's Island, along North Third Street (U. S. 127) between Hamilton and New Miami, was formed when the Great Miami River changed its course after a flood in March 1805. In the 1840s it was bounded on the east and south by the Hamilton Hydraulic canal. According to Mrs. Alta Harvey Heiser, an early owner of the land was Arthur St. Clair Jr., son of the governor of the Northwest Territory. "He resided on his farm above Hamilton and was Butler County's first prosecuting attorney, 1804-1808," said Mrs. Heiser. "After his death, his island homestead was purchased by Dr. Daniel Millikin in 1835.
After Dr. Millikin's death in 1849, L. D. Campbell bought the farm, which is best remembered as Campbell's Island." Later, it was the site of the Ford Airport after the Ford Motor Company plant opened in 1920 south of the island. The area -- the site of a prehistoric village -- also was known as the Ford Farm while it was owned by Henry Ford. The 500-acre Ford Airport was closed in December 1929 and the property was leased to a group of farmers. In the early 1930s, the City of Hamilton paid $47,000 to Miami Farms for 95 acres and established a well field and water treatment plant on part of the island.
