Question: The Roper steam velocipede was built by the inventor and builder from what city?

full_context: Document 1: Sylvester H. Roper: 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.
Document 2: Zadoc Dederick: 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.
Document 3: History of the steam engine: The first recorded rudimentary steam engine was the aeolipile described by Heron of Alexandria in 1st-century Roman Egypt. Several steam-powered devices were later experimented with or proposed, such as Taqi al-Din's steam jack, a steam turbine in 16th-century Ottoman Egypt, and Thomas Savery's steam pump in 17th-century England. In 1712, Thomas Newcomen's atmospheric engine became the first commercially successful engine using the principle of the piston and cylinder, which was the fundamental type steam engine used until the early 20th century. The steam engine was used to pump water out of coal mines
Document 4: R. Tom Sawyer: Robert Thomas Sawyer, known as R. Tom Sawyer, (June 20, 1901 - January 19, 1986) was the inventor of the first successful Gas Turbine Locomotive. He also assisted in development of the diesel locomotive while he worked for General Electric, which led him to be known as the "Father of the Diesel Locomotive". Sawyer was the founder of what is now the modern-day "International Gas Turbine Institute" (IGTI), and among industry professionals was known as "Mr. Gas Turbine". Sawyer authored books about Gas Turbines, Locomotives, and Atomic Power., and was awarded three U.S. Patents. The ASME established the "R. Tom Sawyer Award" to honor him for advancing gas turbine technology in all of its aspects for over 40 years. The award in his name is the highest award given by the IGTI, and is awarded annually at their international "Turbo Expo."
Document 5: Karl Drais: Karl Drais (29 April 1785 – 10 December 1851) was a German inventor, who invented the Laufmaschine ("running machine"), also later called the velocipede, "draisine" (English) or "draisienne" (French), also nicknamed the dandy horse. This incorporated the two-wheeler principle that is basic to the bicycle and motorcycle and was the beginning of mechanized personal transport. Drais also invented the earliest typewriter with a keyboard in 1821, later developed into an early stenograph machine, a meat grinder, and a wood-saving cooker using a hay chest.
Document 6: Christopher Miner Spencer: Christopher Miner Spencer (June 20, 1833 – January 14, 1922) was an American inventor, from Manchester, Connecticut, who invented the Spencer repeating rifle, one of the earliest models of lever-action rifle, a steam powered "horseless carriage", and several other inventions. He developed the first fully automatic turret lathe, which in its small- to medium-sized form is also known as a screw machine.
Document 7: Peugeot Type 1: The Serpollet Tricycle/Peugeot Type 1 is a small steam tricycle, produced by Peugeot in 1886. It is the first Peugeot car ever made.
Document 8: Robert Fulton: Robert Fulton (November 14, 1765 – February 24, 1815) was an American engineer and inventor who is widely credited with developing a commercially successful steamboat called "The North River Steamboat of Claremont". That steamboat went with passengers from New York City to Albany and back again, a round trip of 300 miles, in 62 hours in 1807. In 1800, he was commissioned by Napoleon Bonaparte to attempt to design the "Nautilus", which was the first practical submarine in history. He is also credited with inventing some of the world's earliest naval torpedoes for use by the British Royal Navy.
Document 9: Thompson submachine gun: The Thompson submachine gun is an American submachine gun, invented by John T. Thompson in 1918, that became infamous during the Prohibition era. It was a common sight in the media of the time, being used by both law enforcement officers and criminals. The Thompson submachine gun was also known informally as the "Tommy Gun", "Annihilator", "Chicago Typewriter", "Chicago Piano", "Chicago Style", "Chicago Organ Grinder", "Trench Broom", "Trench Sweeper", "The Chopper", and simply "The Thompson".
Document 10: Colt Ring Lever rifles: The Colt First Model Ring Lever rifle and Colt Second Model Ring Lever rifle are two early caplock revolving rifles that were produced by the Patent Arms Manufacturing Company between 1837 and 1841. The First Model, produced between 1837 and 1838, was the first firearm manufactured by Samuel Colt, developed shortly before the advent of the Colt Paterson revolver. The First Model was succeeded by the Second Model, produced between 1838 and 1841, which featured minor variations in design and construction. Both models are distinguished from later Colt revolving long-arms by the presence of a small ring lever located in front of the trigger. This lever, when pulled, would index the cylinder to the next position and cock the internal hidden hammer. Although complicated in design and prone to failures, fifty First Model rifles were ordered by the U.S. Army for use against Seminole warriors in the Second Seminole War.
Document 11: Webley–Fosbery Automatic Revolver: The Webley–Fosbery Self-Cocking Automatic Revolver was an unusual, recoil-operated, automatic revolver designed by Lieutenant Colonel George Vincent Fosbery, VC and produced by the Webley & Scott company from 1901 to 1924. The revolver is easily recognisable by the zig-zag grooves on the cylinder.
Document 12: Colt's Manufacturing Company: Colt's Manufacturing Company (CMC, formerly Colt's Patent Firearms Manufacturing Company) is an American firearms manufacturer, founded in 1855 by Samuel Colt. It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836. Colt is known for the engineering, production, and marketing of firearms, most especially between the 1850s and World War I, when it was a dominating force in its industry and a seminal influence on manufacturing technology. Colt's earliest designs played a major role in the popularization of the revolver and the shift away from earlier single-shot pistols. Although Samuel Colt did not invent the revolver concept, his designs resulted in the first very successful ones.
Document 13: Michaux-Perreaux steam velocipede: 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.
Document 14: Geneva steam bicycle: The Geneva steam bicycle was a steam powered motorcycle made by the Geneva Cycle Company, Geneva, Ohio in the United States in the late 19th century, in 1896. An example was displayed at "The Art of the Motorcycle" exhibit created by the Guggenheim Museum. The naptha-fired steam engine is based on a design by Lucius Copeland.
Document 15: Roper steam velocipede: 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.
