James Bogardus (March 14, 1800 – April 13, 1874) was an American inventor and architect, the pioneer of American cast-iron architecture, for which he took out a patent in 1850. In the next two decades he demonstrated the use of cast-iron in the construction of building facades, especially in New York City, where he was based, but also in Washington, DC, where three cast-iron structures erected by Bogardus in 1851 were the first such constructions in the capital. The success of the cast-iron exteriors from 1850-1880 led to the adoption of steel-frame construction for entire buildings. Born in Catskill (town), New York, Bogardus quit school at the age of fourteen to start an apprenticeship at a watchmaker. Bogardus attached plaques to his cast-ironwork that read: "James Bogardus Originator & Patentee of Iron Buildings Pat' May 7, 1850." 〔Streetscapes/75 Murray Street; Bought for Its Site, the Rundown Loft Is a Gem, by CHRISTOPHER GRAY, New York Times, October 30, 1994 ()〕 He married Margaret McClay. A small park in TriBeCa, where Chambers Street, Hudson Street and West Broadway (Manhattan) intersect is named ''James Bogardus Triangle.'' He was a descendant of the Rev. Everardus Bogardus (d.1647), the second clergyman in the New Netherlands. Bogardus died in New York City aged 74. Bogardus is interred at Green-Wood Cemetery in Brooklyn, New York. == Notable inventions == * A cotton-spinning machine called a ''ring flier'' (1828) * A mechanized engraving machine (1831), employed for engraving dies for bank notes * The eccentric mill (1832), still used in principle for fine finish of ball bearings, and, with variable eccentricity, for lens grinding. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「James Bogardus」の詳細全文を読む スポンサード リンク
