1854 – mercury vacuum pump

In 1854, Heinrich Geissler invented the mercury displacement vacuum pump, which led to high quality vacuum tubes, which in turn led to the invention of the transistor.

1623 - Pascal - bio

Blaise Pascal was born in 1623 in Clermont, France. He is mostly known as being an outstanding mathematician, but also was a physicist and philosopher. He made significant contributions to the areas of conic sections and projective geometry. Pascal’s triangle is a number matrix in the shape of a triangle with the numbers staggered so […]

1206 – suction pump

In 1206, an Arabic engineer and inventor from Mesopotamia known as al-Jazari wrote a description of a suction pump, along with several other supporting pieces, all incorporated into the design of a twin cylinder reciprocating piston suction pump. This was the first known use of a partial vacuum to suck fluids into a pump, the […]

1650 – vacuum pump

In 1650, Otto von Guericke of Germany, invented the first known vacuum pump.

1855 – vacuum tube

Heinrich Geissler and Julius Plucker use Geisslers new mercury vacuum pump to evacuate the atomosphere inside a glass tube. Plucker, a young professor at the University of Bonn, discovered that a glowing stream could be produced when electricity was passed through electrodes embedded in the glass tubes and that the stream responded to a magnet.
