History
European-Americans started calling their first community "Hole's Station" c. 1797, when Zechariah Hole settled there with his family from Virginia and built a stockade on the west bank of the Miami River opposite the mouth of Bear Creek. The stockade attracted squatters, surveying parties, and other settlers who had taken grants to live in the local cabins until they could build their own; hence the little community became known as "Hole's Station". Settlers came west primarily from Pennsylvania. By 1822, the unincorporated community had become a village; it achieved city status in the 1920s.

By 1827, the was under construction through the community, which improved transportation of people and goods through the region. 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 of times to the canals.

George Kinder, a local resident, shipped bags of food to Ireland during its Great Famine; these also contained his address, with ads saying that he was hiring immigrant workers. Some Irish immigrants did come to Miamisburg and surrounding cities in search of work. By the early 20th century, however, the canal was abandoned. Later, highways carried most of the local traffic.

The Mound Labs were 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 10 mi south of Dayton. The workers, who numbered more than 2,000 at the height of the production, made detonators for. 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 ended, the plant discontinued the detonator work, but it continued to make nuclear power generators for space probes.

In May 1993 U.S Department of Energy decided to end all production at the Mound. This move affected 2,100 employees in the local area. By 1996 cleanup of radioactive and hazardous waste was the main activity at the Plant.

They demolished a house at the Pearl Street crossing and killed three of its five occupants. As a result of a cooperative investigation by the Miamisburg Police Department and the National Transportation Safety Board, the deaths were ruled homicides by the Montgomery County Coroner.

Eight years later, on July 8, 1986, another train derailed on the CSX Transportation line on the west bank of the river, igniting contained in a tanker car. 7,000 local residents were initially evacuated, but during clearing operations the next day another large escape of product resulted in re-ignition of the phosphorus. This led to the evacuation of approximately 30,000 people across southern Montgomery County, the largest evacuation in Ohio history. The resulting thick white cloud engulfed communities as far north as Yellow Springs, Pitchin, and South Vienna. Rolling in like a massive desert dust storm across the horizon, the chemical cloud hugged the ground and blotted out the sun for several minutes before dissipating. 569 persons were treated for "various complaints," more than $3.5 million in property damages occurred, and more than $1 billion in lawsuits resulted.
