Download Verkannte Pioniere: Erfinder, Abenteurer, Visonäre (German by Armin Strohmeyr PDF

By Armin Strohmeyr

Sie wurden von Umwelt und Nachwelt verkannt und verspottet. Ihre Erfindungen wurden gestohlen, sie selbst als Spinner abgetan, unterdrückt, ausgebremst oder weggesperrt: die 22 verkannten Pioniere dieses Bandes.
Wir reisen schnell und bequem mit vehicle und Flugzeug, telefonieren, fotografieren und halten es für selbstverständlich, dass elektrischer Strom aus der Steckdose kommt. Und längst spielen Genetik und Laser auch in unserem Alltag eine segensreiche Rolle.
Die Erfinder dieser Errungenschaften waren zwar geniale Denker, Tüftler und Visionäre, aber meist keine Geschäftsleute und Juristen. Viele von ihnen scheiterten daran, ihre Erfindungen zu patentieren und zu vermarkten. Sie scheiterten an „Kollegen", an der Konkurrenz, an gesellschaftlichen Umständen und meist an der Dummheit anderer. Die Lebensgeschichten dieser Pioniere und die Geschichte ihrer Erfindungen gleichen Abenteuerromanen: Sie sind spannend, tragisch, haarsträubend, bisweilen auch unfreiwillig komisch. Und beinahe unglaublich - wären sie nicht wirklich passiert.
