 Oene Bottema  was professor at Technological University of Delft in the period of  1940-1990 by carrying out an intense activity  for teaching, research, and design in several fields of mechanical engineering, but with specific interests on geometry and theoretical kinematics . He was a personality of reference in his time within national and international frames  because of a  recognized reputation of his works that still today are considered of fundamental importance in geometry and theoretical kinematics .
 Mechanics of machinery, machine design, theoretical kinematics
