John C. Allen

John C. Allen (May 21, 1907 – August 17, 1979) was a roller coaster designer who was responsible for the revival of wooden roller coasters which began in the 1960s. He attended Drexel University. He started working for the Philadelphia Toboggan Company in 1934 as a coaster operator and rose to become president of the company by 1954. He designed more than 25 coasters and made significant contributions to roller coaster technology. He once said, "You don't need a degree in engineering to design roller coasters, you need a degree in psychology." Provided by Wikipedia
