Loammi Baldwin, Jr.
Loammi Baldwin Jr. (May 16, 1780 – June 30, 1838) was an American civil engineer. His father was Col. Loammi Baldwin, a prominent civil engineer. Biography Baldwin was born at North Woburn, Massachusetts living at Baldwin House aka "The Baldwin Mansion", educated at Westford Academy, and graduated from Harvard College in 1800. His early inclinations were towards mechanical subjects, and during his college life he made a clock which kept good time. In 1794 at age 14 he accompanied his father and two brothers (Cyrus, 22, and Benjamin, 17) on a nine-day consulting inspection visit from the famous canal engineer William Weston of the route of the Middlesex Canal. Later all five of Loammi Baldwin Senior's sons (Loammi Baldwin Jr., Benjamin Franklin Baldwin, Cyrus Baldwin, James Fowle Baldwin and George Rumford Baldwin) worked with their father on the ten-year construction of the Middlesex Canal. After graduation, he entered a law office in Groton, Massachusetts, where he construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loammi Baldwin
Colonel Loammi Baldwin (January 10, 1744 – October 20, 1807) was a noted American engineer, politician, and a soldier in the American Revolutionary War. Baldwin is known as the Father of American Civil Engineering. His five sons, Cyrus Baldwin (1773–1854), Benjamin Franklin Baldwin (1777–1821), Loammi Baldwin, Jr. (1780–1834), James Fowle Baldwin (1782–1862), and George Rumford Baldwin (1798–1888), were also well-known engineers. He surveyed and was responsible for the construction of the Middlesex Canal, but today he is perhaps best remembered for the Baldwin apple which he developed at his farm, or rather he recognized its potential and propagated it throughout the northeast. The apple had been discovered on the farm of John Ball in Wilmington, Massachusetts, around 1750, and named Woodpecker by a later owner of the farm. Colonel Baldwin's promotion of the apple occurred after 1784. He was also a surveyor and plantation co-owner in Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlestown, Massachusetts
Charlestown is the oldest neighborhood in Boston, Massachusetts, in the United States. Originally called Mishawum by the Massachusett tribe, it is located on a peninsula north of the Charles River, across from downtown Boston, and also adjoins the Mystic River and Boston Harbor waterways. Charlestown was laid out in 1629 by engineer Thomas Graves, one of its earliest settlers, during the reign of Charles I of England. It was originally a separate town and the first capital of the Massachusetts Bay Colony. Charlestown became a city in 1848 and was annexed by Boston on January 5, 1874. With that, it also switched from Middlesex County, to which it had belonged since 1643, to Suffolk County. It has had a substantial Irish-American population since the migration of Irish people during the Great Irish Famine of the 1840s. Since the late 1980s, the neighborhood has changed dramatically because of its proximity to downtown and its colonial architecture. A mix of yuppie and upper-mid ...

Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bunker Hill Monument
The Bunker Hill Monument is a monument erected at the site of the Battle of Bunker Hill in Boston, Massachusetts, which was among the first major battles between the Red Coats and Patriots in the American Revolutionary War. The 221-foot (67 m) granite obelisk was erected between 1825 and 1843 in Charlestown, Massachusetts, with granite from nearby Quincy conveyed to the site via the purpose-built Granite Railway, followed by a trip by barge. There are 294 steps to the top. An exhibit lodge built near the base of the monument in the late 19th century houses a statue of fallen hero Dr. Joseph Warren. Bunker Hill is one of the sites along the Freedom Trail and is part of Boston National Historical Park. The monument underwent a $3.7 million renovation, completed in 2007, that included repairs, handicap accessibility improvements, and new lighting. The Bunker Hill Museum across the street was dedicated in June of that year and includes many exhibits about the battle. No admission ch ...

Union Canal (Pennsylvania)
The Union Canal was a towpath canal that existed in southeastern Pennsylvania in the United States during the 19th century. First proposed in 1690 to connect Philadelphia with the Susquehanna River, it ran approximately 82 mi from Middletown on the Susquehanna below Harrisburg to Reading on the Schuylkill River. Construction began in 1792 during the George Washington Administration, but financial difficulties delayed its completion until 1828. Called the "Golden Link," it provided a critical early transportation route for shipping anthracite coal and lumber eastward to Philadelphia. Closed in the 1880s, remnants of the canal remain, most notably the Union Canal Tunnel, a hand-built engineering marvel that is the oldest existing transportation tunnel in the United States. The tunnel is a National Historic Landmark.

Boston Harbor
Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston, a major shipping facility in the northeastern United States. History Since its discovery to Europeans by John Smith in 1614, Boston Harbor has been an important port in American history. Early on, it was recognized by Europeans as one of the finest natural harbors in the world due to its depth and natural defense from the Atlantic as a result of the many islands that dot the harbor. It was also favored due to its access to the Charles River, Neponset River and Mystic River which made travel from the harbor deeper into Massachusetts far easier. It was the site of the Boston Tea Party, as well as almost continuous building of wharves, piers, and new filled land into the harbor until the 19th century. By 1660, almost all imports came to the greater Boston area and the New England coast through the waters of Boston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
