Gregory was apprenticed to John Fowler in 1732〔(【引用サイトリンク】url=http://collections.rmg.co.uk/collections/objects/42500.html )〕 and was himself in business from c. 1750–1792 from premises in Francis Court, Clerkenwell, London and an establishment known as "The Azimuth Compass" in Leadenhall Street, London.〔(【引用サイトリンク】url=http://www.bodley.ox.ac.uk/johnson/exhibition/005.htm )〕 His company later became known as Gregory and Son. Gregory manufactured navigational instruments, including quadrants of the type invented by John Hadley and compasses. One of his azimuth compasses traveled with the explorer James Cook on his second voyage to the southern Pacific Ocean in 1772–1775. An azimuth compass is a compass fitted with vertical sights, used to take the magnetic azimuth of a star or planet. Surviving examples of the azimuth compass exist in the collections of the National Maritime Museum, Greenwich〔(【引用サイトリンク】url=http://collections.rmg.co.uk/collections/objects/42500.html )〕 and the Smithsonian National Museum of American History.〔(【引用サイトリンク】url=http://amhistory.si.edu/navigation/object.cfm?recordnumber=1197884 )〕 ==References== * 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「Henry Gregory (instrument maker)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
