Baron Wilhelm Theodor Unge was a military engineer who invented a telemeter and various improvements to artillery.〔(【引用サイトリンク】url=http://www.nmspacemuseum.org/halloffame/detail.php?id=40 )〕 He was born in Stockholm, Sweden in 1845. He worked with Alfred Nobel to improve the range and accuracy of Hale rockets, by using improved propellants and launching from cannons.〔 It is possible that one of his rockets carried the Nobel camera that made the first aerial photograph from a rocket in April 1897.〔 After Nobel died in 1896, Unge obtained patents for improved rockets with some sold to several countries. In 1908 he sold his patents to Friedrich Krupp.〔 ==See also== *Hale rockets *Aerial photography *Aerial reconnaissance 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「Wilhelm T.
