E&F Miler was founded in the late 1940’s in Portland, Oregon, USA, by Carl Miler under the name of Miler Manufacturing. They specialized in family and Wild Mouse roller coasters, which were built exclusively in the USA between the 1940’s and 70’s, after which the company ceased building new coasters. Miler Manufacturing was reopened in 1989 by Carl’s son, Fred Miler. The first coaster to be built under Fred’s watch was The Great Pumpkin Coaster at Kings Island in Ohio, USA, in 1992, which coincided with another company name change to Miler Coaster, Inc. Carl Miller passed away in 2001, and the company changed its name to E&F Miler Industries in 2013 when Fred’s son, Eric, joined the board.











In the early 1940s, E&F Miler built oval kiddie coasters at Playland Pier in Idaho and Funderland Amusement Park in California, USA. The one in Coeur d’Alene opened in 1942, but the exact date of the one in Sacramento is unknown, and it’s anyone’s guess as to which came first.
The first D.H. Morgan coaster was Wild Thing at Valleyfair in Minnesota, USA, which opened in 1996. It’s a 207 feet (63m) tall, 74 mph (119 km/h) Hyper Coaster that open two weeks before the above mentioned Quicksilver Express family coaster. When it opened, Wild Thing was the third tallest coaster in the world following the two Arrow Dynamic Hyper Coasters – Big One at Blackpool Pleasure Beach in the UK and Desperado at Buffalo Bill’s Resort & Casino in Nevada, USA.
