Originally, the small community had been known as “Holes’ Station” since about 1797, when Zachariah Hole settled there with his family from Virginia and built a stockade on the west bank of the Miami River opposite from the mouth of Bear Creek. Along with the stockade brought Squatters, Surveying Parties, and other settlers who had taken grants out for them to live in the local cabins until they could build their own ; hence the little community became known as “Hole’s Station”. Meanwhile more settlers poured into the town from all over but mainly from Pennsylvania. The name Miamisburg comes from the words “Miamis” and “burg” just combined together. By 1822 the unincorporated community had become a village and achieved city status about 100 years later.
By 1827, the Miami and Erie Canal was under construction which passed through the community and made transportation of people and goods very convenient. The formal opening took place in January 1829, when the “Governor Brown” was the first packet boat to go through the settlement. Also that year the first boats from Cincinnati had arrived and passed through Miamisburg to get to Dayton. By 1834 the canal had been extended to Piqua and many businesses along the river grew. The 1840s and the 1850s were brought the best to the canals. The canal can also be credited for bringing in new Irish citizens during the famine in Ireland. A local resident George Kinder shipped bags of food to Ireland also containing his addresses and many papers stating that he was hiring immigrant workers. Years later there was a surge of Irish immigrants to the area and surrounding cities. But by the early 1900s the Canal was abandoned and later replaced by highways.
Miamisburg was the site of one of the first post-war U.S Atomic Energy Commission facilities, beginning in 1947. The Dayton area had supported numerous secret operations for the War Department during World War II. As the war ended the majority of these operations were moved to the Miamisburg Mound Laboratory which was operated by the Monsanto Chemical Company. The primary purpose of Mound Labs was to monitor all aspects of the US nuclear defense stockpile.
The Mound Plant, built in 1947, was situated on a 306–acre site in the city south of Dayton. The workers, who numbered more than 2,000 at the height of the production, made plutonium detonators for nuclear weapons. Their work was very classified. The plant had a small army of security guards and was ringed by chain-link fencing and razor wire. When the Cold War ended, the plant discontinued the detonator work but continued the make a generators for space probes. In May 1993 U.S Department of Energy decided to end the all productions at the Mound. This move would affect 2,100 employees in the local area. By 1996 cleanup of radioactive and hazardous waste was the main activity at the Plant. Local business had to decide what would become of the empty plant.
On July 8, 1986, a train derailed on the CSX line on the west bank of the Great Miami River, igniting phosphorus contained in some of the tanker cars. This led to the evacuation of approximately twenty thousand people across southern Montgomery County, the largest evacuation in Ohio history. More than one billion dollars in lawsuits resulted.
