On this site Daniel Gebhart established a tavern in 1811. Taverns were where people gathered to eat, rest, and share news. During spring freshets, boatmen from the Great Miami River stayed at the tavern. Joining them were pioneers coming by the river and overland to settle at Hole’s Station, now Miamisburg. The tavern closed in 1840, became a boarding house, and then sold to become a private residence in 1853. To commemorate the nation’s Bicentennial in 1976, Miamisburg’s bicentennial committee purchased the tavern and gave it to the city. It was restored and opened as a museum in 1982.

In late March 1913, a series of three severe rainstorms inundated the already saturated and frozen ground of the Miami Valley, causing one of Ohio’s greatest natural disasters, the Flood of 1913. On March 25, the Great Miami River overflowed its banks at Miamisburg, fed by runoff from Bear and Sycamore creeks. Homes, businesses, and the bridges at Linden Avenue and Sycamore Street were swept away or wrecked by floodwaters reaching as high as eleven feet on Main and First streets. Early reports indicated that six people in the area died. Cleanup and recovery efforts took approximately a year. (Continued on other side)

The facilities once here propelled the United States through the Nuclear and Space Ages and were named for the nearby pre-historic Miamisburg Mound. The Manhattan Engineer District of the War Department began construction of Mound Laboratory in 1946. The facility consolidated production of the nuclear-reaction initiators, developed for the United States’ first atomic bombs during World War II. Previously (1943-1946), the work to separate, purify, and process the element polonium used in these initiators occurred at facilities throughout the Dayton area. Mound Laboratory was the nation’s first permanent post-WWII Atomic Energy Commission site. Mound Laboratory had 116 buildings and at its peak employed approximately 2,500 scientists, engineers, and skilled workers. Contractors operating at the site were Monsanto (1947-1988), Edgerton, Germeshausen, and Grier (1988-1997), and Babcock and Wilcox (1997-2002). (Continued on other side)
