Carl von LindeDied 16 Nov 1934 at age 92 (born 11 Jun 1842).German chemist, engineer and inventor who invented mechanical refrigeration. His first refrigeration equipment was tested in a Munich brewery. Brewing good lager beer required low temperatures, limiting brewing to winter, or in deep cellars with the use of large quantities of block ice. Through Linde's invention of refrigeration, beer brewing became seasonally independent. Linde also invented a continuous process of liquefying gases in large quantities which provided both impetus and means for conducting scientific research at low temperatures and very high vacuums. Linde's original industry has now grown to 120 companies around the world. |
