Curtis D. Summers

Curtis D. Summers (September 17, 1929 – May 11, 1992) was an American engineer and roller coaster designer credited for designing or providing structural engineering on 25 wooden roller coasters around the world. He earned a degree in Architectural Engineering from Kansas State University and was a registered engineer in 40 states. The owners of Coney Island, Taft Broadcasting, closed the park in order to escape the repeated flooding from the Ohio River and built a new park, Kings Island, 25 miles to the north. Summers was asked to design most of the structures of the new park and worked alongside John C. Allen to assist him by providing the structural engineering on the two new wooden coasters constructed for the park.

The Taft Broadcasting Company, and its successor, Kings Entertainment Company (KECO), went on to build two more amusement parks, Kings Dominion and Canada's Wonderland. They purchased an existing park, Carowinds; managed California's Great America and were co-owners of Australia's Wonderland. Curtis D. Summers and his firm continued to be the primary engineers for each of the parks. When John Allen retired from the coaster-building business in 1976, Summers took over as the primary designer of wooden coaster projects for the Taft/KECO chain of amusement parks.

In 1978 KECO started building The Beast at Kings Island. Summers' firm was brought on board to provide structural engineering for the massive helix finale. The project was built in-house and was overseen by Charles (Charlie) Dinn, Kings Island's Director of Construction, Maintenance and Engineering. Dinn left Kings Island in 1984 to start his own firm the Dinn Corporation. In 1985 he contacted Summers' firm to provide the design for the restoration of the helix of Paragon Park's Giant Coaster which Dinn was moving to Wild World in Largo, Maryland.
