Richard E. Schreder grew up in Toledo, Ohio and graduated from the University of Toledo with a degree in Mechanical Engineering. He was a decorated navy pilot and iconic aviation figure who helped shape the American soaring movement, international glider design, and competitive soaring and piloting flight strategies. He also made high performance gliders available to a wide audience through the affordable kit production of his distinctive HP (High Performance) glider designs. These designs and Schreder’s numerous contributions to aviation and the sport of soaring are recognized as “groundbreaking and pioneering” by the Smithsonian Museum and are part of the Smithsonian National Air & Space Museum’s permanent collection.

On December 15, 1967, about one mile downstream from this historic marker, a national tragedy occurred. Forty-six interstate travelers lost their lives when the Silver Bridge collapsed into the Ohio River during five o’clock rush hour traffic. The 2,235 foot two-way vehicular bridge connected Point Pleasant, West Virginia and Kanauga, Ohio via U.S. Route 35. The West Virginia Ohio River Company built the structure in 1928 for $1.2 million. The bridge, unique in its engineering conception, was the first of its design in America and the second in the world. Instead of woven-wire cable, the bridge was suspended on heat-treated eye-bar chains. It was named the “Silver Bridge” because it was the first in the world to be painted with aluminum paint. In 1969, two years later, its replacement, the Silver Memorial Bridge was dedicated.

On October 3, 1920 the first game matching two professional teams of the American Professional Football Association, a league that would become the National Football League (NFL), was held on this field within Triangle Park. In that game, the Dayton Triangles defeated the Columbus Panhandles 14-0. The Triangle’s Lou Partlow scored the first touchdown and George “Hobby” Kinderdine kicked the first extra point. Three factories founded by Dayton businessmen Edward Deeds and Charles Kettering sponsored the Dayton Triangles team. The factories were the Dayton Engineering Laboratories Company (DELCO), Dayton Metal Products Company (D.M.P.Co.), and Domestic Engineering Company (DECO), later call Delco-Light. They formed an industrial triangle of plants in downtown Dayton.

Stephen and Viola Armstrong moved their family, including 13-year-old Neil and his younger siblings, June and Dean, to the house at 601 West Benton Street in 1944. Here, Neil explored his fascination with flying by reading aviation magazines and building model airplanes. Neil completed flying lessons at nearby Port Koneta airport and earned his pilot’s license on his sixteenth birthday, even before receiving a driver’s license. Neil graduated from Blume High School in 1947 and studied aeronautical engineering at Purdue University on a Navy scholarship. The Korean conflict interrupted his studies, but he left the Navy as a decorated combat pilot, flying 78 missions. After graduating from Purdue in 1955, Neil worked at what would become the NASA Glenn Research Center in Cleveland. Soon after he became a test pilot at Edwards Air Force Base in California.

The Village of Tadmor is significant as being the location of one of the most important centers of transportation in early Ohio history. As early as 1809, keelboats were poled up river from Dayton to load and unload freight in the village. By 1837, the Miami and Erie Canal had reached Tadmor, connecting it to the Ohio River in the south and Lake Erie in the north. In the 1830s, the National Road was constructed through Tadmor, connecting it to points east and west. In 1851, the Dayton & Michigan Railroad established freight and passenger service to the growing town. Residents hoped that Tadmor’s strategic location would help it prosper, however, successive flooding on the Great Miami River stifled growth. Tadmor was finally abandoned when a dam constructed by the Miami Conservancy District in 1922 to retain water during flooding made the site uninhabitable.

Major General William Sooy Smith was born in Tarlton on July 22, 1830. He attended Ohio University and supported himself throughout his college undergraduate career, graduating in 1849. He then entered the United States Military Academy at West Point to pursue engineering and graduated 6th in the class of 1853. In 1857, Smith established the private engineering firm Parkinson & Smith and made the first surveys for the international bridge across the Niagara River near Niagara Falls. At the outbreak of the Civil War, Smith joined the 13th Ohio Infantry, winning the commission of colonel in June 1861. After early victories in western Virginia, he was promoted to brigadier general in April 1862 for his gallant and meritorious service at the Battle of Shilo. (continued on other side)

The Marion Mausoleum represents a time in early 20th-century America in which burial practices changed because of advances in engineering and construction materials, concerns about hygiene, and a new rise in wealth among the middle class. Exhibiting elements of the Neo-Classical Revival and Prairie architectural styles, construction of the sandstone building began in 1906. The mausoleum opened to the public in 1916. The interior is comprised of marble and concrete. Furnishings include chandeliers, wool carpeting, and wrought iron furniture. Stained-glass windows admit natural light. Two windows feature an upside-down torch with a still-burning flame, which symbolizes a belief in eternal spiritual life after death and burial. The mausoleum has space for 383 internments. As of 2016, it is supported and maintained by a perpetual care fund.

Early in 1942, during World War II, the U. S. Army Corps of Engineers acquired 640 acres along two miles of U. S. Route 30 South (now State Route 309) from ten landowners. By June 11 of that year, the farm families were removed and construction of The Marion Engineer Depot (MED) began, costing $4 million. The first military encampment in Marion County, the 333rd Engineering Regiment, arrived in May and established its camp in a wheat field. They lived in tents while constructing streets and railroad tracks around the Depot. MED was dedicated on December 7, 1942. During the war, food, munitions, equipment, and other military supplies flowed in and out of MED and heavy machinery was renovated. Peak employment came in July 1944 with 1,487 civilian and 47 military personnel on site. (Continued on other side)
