,Ferdinand Freudenstein (1926–2006),ults in every area of modern kinematics. At the time of his death there were over 500 academic descendents belonging to the Freudenstein family tree. His progeny are teachers in many different countries, and his research results have shaped the teaching and practice of mechanism and machine theory throughout the world.

,Kurt Hain (1908–1995),ere are notions, procedures and methods that are strongly connected with his name. His kinematic heritage for future generations of mechanical engineers is now preserved in the framework of a national research project in Germany, named “DMG-Lib”.

Basic Notions of JasperReports,rote almost 50 papers on kinematics. Most of them contain original contributions. He invented the method of instantaneous invariants in instantaneous kinematics. With Bernard Roth he wrote the influential survey ., North Holland, Amsterdam, 1979.

,Archimedes (287–212 BC),atized the design of simple machines and the study of their functions. He was probably the inventor of the compound pulley and developed a rigorous theory of levers and the kinematics of the screw. He is the founder of statics and of hydrostatics, and his machine designs fascinated subsequent writer

,Oene Bottema (1901–1992),s had turned away from classical geometry. At the same time kinematics continued to play an important role in mechanical engineering. The engineers needed a man like Bottema who applied his encyclopedic knowledge of 19th century geometry with 20th century precision to many kinematical problems. He w

One of the main achievements that he is remembered for is his pioneering work on integrating Hamilton’s . with Grassmann’s . into a more general coherent corpus, now referred to eponymously as Clifford alg

His work is considered to be the most fundamental contribution ever made to the mechanics of celestial bodies. The p
