Franz Grashof (11 July 1826 – 26 October 1893) was a German engineer. He was a professor of Applied Mechanics at the Technische Hochschule Karlsruhe. ==Biography== Born in Duesseldorf (Germany) as the son of Elisabeth Brüggemann and Karl Grashof, who taught at an upper secondary school, Franz Grashof visited the elementary and lower secondary school in Duesseldorf and the industrial school in Hagen. Motivated by the rise of steamers and the railway, he started working at a locksmith’s shop. In October 1844 Franz Grashof quit school to start studying metallurgy at the royal vocational institute in Berlin. Therefore he studied mathematics, physics and mechanical engineering. From 1847 to 1848 he interrupted his studies to voluntarily serve for the military. To serve his country he aimed at becoming a marine officer. Therefore he had to start working as a simple sailor on a sailing ship called “Esmeralda”. Until December 1851 he sailed around the world and realized that practical work was not his main professional skill. On his journey he decided to teach at a technical school. That’s why he carried on studying in Berlin in 1852. In 1854 Franz Grashof concluded his studies and became a teacher in mathematics and mechanics at the royal vocational institute in Berlin. In 1855 he got the leadership of the royal gauging office in Berlin. In the following year he was involved in the establishment of the Association of German Engineers and became its managing director until 1890. From 1863 to 1891 he was a professor of General and Theoretical Machine Science at the Technische Hochschule Karlsruhe. He developed some early steam-flow formulas but made significant contribution to free convection.〔 On October 26, 1893 he died after his second stroke. 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「Franz Grashof」の詳細全文を読む スポンサード リンク
