Question: What nationality was the designer of the Volcano in Doswell, Virginia?
Context: The Virginia Central Railroad was an early railroad in the U.S. state of Virginia that operated between 1850 and 1868 from Richmond westward for 206 mi to Covington.  Chartered in 1836 as the Louisa Railroad by the Virginia General Assembly, the railroad began near the Richmond, Fredericksburg and Potomac Railroad's line and expanded westward to Orange County, reaching Gordonsville by 1840.  In 1849, the Blue Ridge Railroad was chartered to construct a line over the Blue Ridge Mountains for the Louisa Railroad which reached the base of the Blue Ridge in 1852.  After a decision from the U.S. Supreme Court, the Louisa Railroad was allowed to expand eastward from a point near Doswell to Richmond. Flight of Fear (previously known as The Outer Limits: Flight of Fear) is an enclosed launched roller coaster at two Cedar Fair parks, Kings Island in Mason, Ohio and Kings Dominion in Doswell, Virginia.  Both Flight of Fear roller coasters first opened in 1996 and were the world's first roller coasters to feature a linear induction motor (LIM) launch.  Flight of Fear has won three awards from the International Association of Amusement Parks and Attractions, including one for Major Theme/Amusement Park Ride/Attraction and two for Technology Applied to Amusements. Smurf Mountain was a train ride at Kings Dominion in Doswell, Virginia, United States. Doswellia is an extinct genus of archosauriform from the Late Triassic of North America.  It belongs to the family Doswelliidae, which also includes the genera "Archeopelta" and "Tarjadia" from South America.  "Doswellia" was a terrestrial carnivore that reached a length of 2 m (7 ft) and lived during the Carnian stage of the Late Triassic.  It possesses many unusual features including a wide, flattened head with narrow jaws and a box-like rib cage surrounded by many rows of bony plates.  The type species "Doswellia kaltenbachi" was named in 1980 from fossils found within the Poor Farm Member of the Falling Creek Formation in Virginia.  The formation, which is found in the Taylorsville Basin, is part of the larger Newark Supergroup.  "Doswellia" is named after Doswell, the town from which remains have been found.  A second species called "D. sixmilensis" was described in 2012 from the Bluewater Creek Formation of the Chinle Group in New Mexico. Doswell is an unincorporated community in Hanover County in the Central Region of the U.S. Commonwealth of Virginia.  Originally called Hanover Junction, it was located on the Virginia Central Railroad, which later became part of the Chesapeake and Ohio Railroad (C&O) at a crossing of the Richmond, Fredericksburg and Potomac Railroad, a north-south route.  Both railroads are now owned by CSX Transportation, although the former Virginia Central line is leased to a short-line carrier, Buckingham Branch Railroad.  The area near the Doswell train station is a popular train-watching site for railfans. The Crypt (formerly Tomb Raider: Firefall) is a HUSS Park Attraction suspended Top Spin ride located at Kings Dominion in Doswell, Virginia.  The Crypt was also the name of a giant top spin at Kings Dominion's sister park, Kings Island (Kings Island's version closed on October 30, 2011 while the Kings Dominion version still operates).  Both rides were originally themed after the movie , until Kings Dominion, Kings Island, and the other three Paramount Parks were sold to the Cedar Fair Entertainment Company. Volcano, The Blast Coaster, or simply Volcano, is a launched inverted roller coaster at Kings Dominion in Doswell, Virginia.  Designed by both Paramount Parks and Werner Stengel and built by Intamin, Volcano was the world's first inverted roller coaster to feature an LIM (linear induction motor) and is the only one of its kind that completes a full circuit.  Since its opening on August 3, 1998, Volcano has been one of the more popular rides in the park.  Most of Volcano's circuit is located inside a man-made volcano, making it an enclosed roller coaster. Werner Stengel (born 22 August 1936 in Bochum) is a German roller coaster designer and engineer.  Stengel is the founder of Stengel Engineering, also known as Ingenieur Büro Stengel GmbH (or Ingenieur Buero Stengel GmbH). The Falling Creek Formation, also known as the Falling Creek Member, is a unit of Upper Triassic sedimentary rocks found in the Taylorsville Basin of Virginia.  It forms the middle part of the Doswell Group, beneath the Newfound Formation and above the South Anna Formation.  This approximately 2000 ft thick unit is of middle Carnian age and has a varied lithology, consisting of sandstone, siltstone, shale, limestone and coal.  It was named after the Falling Creek near Ashland, Virginia.  The type section is found in outcrops along the Stagg Creek in Hanover County. Intimidator 305 is a steel roller coaster located at Kings Dominion in Doswell, Virginia, United States.  Manufactured by Intamin, Intimidator 305 opened to the public on April 2, 2010, as the park's fourteenth roller coaster.  The roller coaster is located in the Safari Village section of the park near Anaconda on the former site of the Safari Monorail ride.  Standing at 305 ft tall and reaching speeds of 90 mph , it is the second Giga Coaster to be built in North America – the first was Millennium Force at Cedar Point.  The $25 million investment was the largest of any ride in the park's history.  It is named and themed after NASCAR driver Dale Earnhardt, who was also known as the "Intimidator."
