100th birthday - Austria / II. Republic of Austria 1987 - 5 Shilling

The physicist Erwin Schrödinger was born on August 12, 1887 in Vienna. From 1906 to 1910 he studied physics at the University of Vienna. In the First World War he was employed as an artillery officer on the Isonzo front, but survived the war without illness or injury. In 1920, he was awarded the Haitinger Prize of the Vienna Academy of Sciences for his investigations in the summer of 1913 in Seeham (north of Salzburg) conducted on atmospheric electricity. Based on the hypothesis of the French physicist Louis de Broglie, that not only light, but also electrons and all matter at the same time should possess particle properties and wave properties, Schrödinger succeeded in 1926 in establishing his famous differential equation. He combined mechanics and wave conception, thus founding the "wave mechanics", about which more than 100,000 physical publications exist today. In 1933, Erwin Schrödinger, together with P.A.M. Dirac the Nobel Prize for Physics. Many other awards and honors were given to the brilliant researcher in the course of his life still. Schrödinger died on 4 January 1961 in Vienna and was buried according to his wishes on the small mountain cemetery in Alpach.
