Ferdinand Freudenstein is an American physicist and engineer who is considered to be the "Father of Modern Kinematics." Freudenstein made revolutionary contribution applying digital computation to the kinematic synthesis of mechanisms.〔M. Checcarelli (Editor), 2007, ''Distinguished Figures in Mechanism and Machine Science,'' Springer. http://www.springerlink.com/content/p68g683357756307/fulltext.pdf?page=1 Life and career of Ferdinand Freudenstein〕 In his Ph.D dissertation, Freudenstein developed what is to become the Freudenstein Equation, which uses a simple algebraic method to determine the position of an output lever in a linkage mechanism.〔http://columbiauniversity.org/cu/mechanical/announcements/033006Freudenstein/index.html〕 Freudenstein spent his entire career working and teaching in Columbia University as the Higgins Professor of Mechanical Engineering. Over his life-time, Freudenstein mentored over 500 Ph.D. students in hundreds of universities across the world. ==Early life== Ferdinand Freudenstein was born into a Jewish family, on May 12, 1926, in Frankfurt, Germany. He was the son of a successful merchant George Freudenstein and Charlotte Rosenberg. At the age of ten, Freudenstein with his parents and two sisters fled Nazi Germany for refuge in the Netherlands. In the spring of 1937, Freudenstein moved to England after having spent six months in the city of Amsterdam. In England, he joined his brother and studied in London. During Hitler's blitzkrieg, Freudenstein temporarily moved to Cambridge, England, for safety, and then spent several years in Llandudno, North Wales. Meanwhile, his father and brother were sent to exile in Australia by the British government which regarded all adult male German citizens as enemy of the state. In 1942, when he was 16 years old, Ferdinand with his mother and two sisters sailed from England to Trinidad where they remained for six weeks before moving permanently to the United States. 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「Ferdinand Freudenstein」の詳細全文を読む スポンサード リンク
