Task: Question Answering
Input (English): Context_1 : William Mason is a 4-4-0 steam locomotive currently in operation at the Baltimore and Ohio Railroad Museum in Baltimore, Maryland, United States. It was built for the Baltimore and Ohio Railroad, carrying that railroad's number 25. The locomotive is named in honor of its builder, William Mason, who built around 754 steam locomotives at his Mason Machine Works firm in Taunton, Massachusetts, from 1853 until his death in 1883. The engine is one of the oldest operable examples of the American Standard design, and the fourth oldest Baltimore and Ohio locomotive in existence, the oldest being the 0-4-0 no. 2, the "Andrew Jackson" from 1836, second oldest is the no. 8 0-4-0, "John Hancock" built later that same year, and the third being the 0-8-0 no. 57, "Memnon" of 1848 (the preserved "Tom Thumb" and "Lafayette" engines are replicas built by the road for exhibition purposes in 1926 and 1927, respectively). The "William Mason" had been the second oldest operational locomotive in the world, and the oldest in the western hemisphere. Only the Indian locomotive "Fairy Queen", built one year prior to the "William Mason" is older. Context_2 : The Roper steam velocipede was a steam-powered velocipede built by inventor Sylvester H. Roper of Roxbury, Boston, Massachusetts, United States sometime from 1867–1869. It is one of three machines which have been called the first motorcycle, along with the Michaux-Perreaux steam velocipede, also dated 1867–1869, and the 1885 Daimler "Reitwagen". Historians disagree over whether the Roper or the Michaux-Perreaux came first. Though the "Reitwagen" came many years later than the two steam cycles, it is often, perhaps most often, known as the "first motorcycle" because there is doubt by some experts that a steam cycle meets the definition of a motorcycle. Context_3 : James Peter Allaire (July 12, 1785 – May 20, 1858) was a noted master mechanic and steam engine builder, and founder of the Allaire Iron Works (est. 1815), the first marine steam engine company in New York City, and later Howell Works (est. 1822), in Wall Township, New Jersey. His credits also include building both the first compound steam engine for marine use and the first New York City tenement structure. Context_4 : Zadoc P. Dederick was an American inventor. Along with Isaac Grass he was the creator of a steam-powered humanlike robot designed to pull a cart. The invention was patented on March 24, 1868, as patent 75874, and operated through a system of levers and cranks, attached to steam-powered pistons and a boiler. The original prototype cost $2000 (about $32,487 in modern US dollars) and was built in Newark, New Jersey. Plans to produce it for $300 never went through, making this an example of an early development in steam power that was abandoned. Nonetheless, inventions such as this one spurred interest in steam power, as exemplified by novels such as "The Steam Man of the Prairies", and by many imitations and hoaxes that appeared as a result. Context_5 : Athena was a 50 m long passenger steamship built in 1893 at the Syros (later Neorion) Shipyards. It was the first metal steamship built at this shipyard, and it represented an example of the brief growth of Greek shipbuilding in the late 19th century, before its decline in the next decades. The ship was powered by a steam engine built by the Ifaistos machine works in Piraeus, the second largest machine builder in the country (after Basileiades) at the time; Ifaistos was founded by John McDowall, a Scottish entrepreneur who had worked in Greece and had obtained Greek citizenship, and was the main builder of ship steam engines in Greece. This ship (renamed "Rafiah") sank in 1946 in a tragic accident that claimed the lives of Jewish refugees. Context_6 : Joshua C. Stoddard (August 26, 1814 in Pawlet, Vermont – April 4, 1902) was an American inventor. He was educated at the public schools, and became noted as an apiarist. He also turned his attention to inventing, and on October 9, 1855, patented (U.S. Patent  ) the steam calliope, used on Mississippi steamerboats. It was originally known as a "steam piano", with Stoddard forming the American Steam Piano Company [sometimes referred to as the American Steam Music Company] in Worcester, Massachusetts. His first instrument, consisting of a steam boiler, a set of valves, and fifteen graded steam whistles played from a pinned cylinder, reportedly could be heard for a range of 5 mile . The Worcester City Council banned him from playing it within the city limits because it was so loud. Context_7 : Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer from Cornwall, England. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He performed poorly in school, but went on to be an early pioneer of steam-powered road and rail transport. His most significant contribution was the development of the first high-pressure steam engine. He also built the first full-scale working railway steam locomotive. On 21 February 1804 the world's first locomotive-hauled railway journey took place as Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Context_8 : The Michaux-Perreaux steam velocipede was a steam powered velocipede made in France sometime from 1867 to 1871, when a small Louis-Guillaume Perreaux commercial steam engine was attached to a Pierre Michaux manufactured iron framed pedal bicycle. It is one of three motorcycles claimed to be the first motorcycle, along with the Roper steam velocipede of 1867 or 1868, and the internal combustion engine Daimler Reitwagen of 1885. Perreaux continued development of his steam cycle, and exhibited a tricycle version by 1884. The only Michaux-Perreaux steam velocipede made, on loan from the Musée de l'Île-de-France, Sceaux, was the first machine viewers saw upon entering the Solomon R. Guggenheim Museum rotunda in The Art of the Motorcycle exhibition in New York in 1998. Context_9 : Raymond Saunders is a Canadian clockmaker who has designed and built more than 150 customized clocks that mainly serve as tourist-attracting public artworks. In 1977 he was commissioned to build a steam clock for the Gastown district of Vancouver, Canada. The Gastown clock may be the first steam clock ever built, although there is evidence that 19th century British engineer John Inshaw made a steam clock after which was named a Birmingham pub. Saunders has since built six different public steam clocks for clients such as the city of Otaru, Japan, and the Indiana State Museum. He has also built a clock for Vancouver's York House School's 78th birthday in 2010. Context_10 : Sylvester Howard Roper (November 24, 1823 – June 1, 1896) was an American inventor and a pioneering builder of early automobiles and motorcycles from Boston, Massachusetts. In 1863 he built a steam carriage, one of the earliest automobiles. The Roper steam velocipede of 1867–1869 may have been the first motorcycle, for which he was inducted into the Motorcycle Hall of Fame in 2002. He is also the inventor of the shotgun choke and a revolver repeating shotgun. fact_1 : The Roper steam velocipede was a steam-powered velocipede built by inventor Sylvester H. Roper of Roxbury, Boston, Massachusetts, United States sometime from 1867–1869. fact_2 : Sylvester Howard Roper (November 24, 1823 – June 1, 1896) was an American inventor and a pioneering builder of early automobiles and motorcycles from Boston, Massachusetts. Question: The Roper steam velocipede was built by the inventor and builder from what city?
Output (English): Boston, Massachusetts
