[PAR] [TLE] Vacuum pump [SEP] A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum.  The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [PAR] [TLE] Otto von Guericke [SEP] Otto von Guericke (originally spelled "Gericke", ] ; November 20, 1602 – May 11, 1686 (Julian calendar); November 30, 1602 – May 21, 1686 (Gregorian calendar)) was a German scientist, inventor, and politician.  His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for clearly demonstrating electrostatic repulsion, and his advocacy of the reality of "action at a distance" and of "absolute space".
