Charles J. Dinn was the director of construction, maintenance, and engineering at Kings Island and oversaw construction of The Beast, which opened in 1979. Dinn went on to form his own company in the early 1980s. The company managed the construction of wooden roller coasters in partnership with Curtis D. Summers' company.
Construction began on Pegasus at Efteling in late 1990 but Dinn abandoned the project following disagreements with Efteling and ultimately retired in 1991. His daughter Denise Dinn formed a new company, Custom Coasters International. Summers died the following year of a heart attack at the age of 62.
