Werner Stengel first worked with Anton Schwarzkopf in 1963 to help design the first few Schwarzkopf roller coasters. Stengel recognized how important design was to the coaster industry, which encouraged him to found his own Engineering firm in 1965. In total, Stengel Engineering (now Ing.-Büro Stengel GmbH) has designed over 450 coasters; so much so that an estimated 3/4 of the world’s top steel coasters had direct involvement from Stengel Engineering.
