List of German inventions and discoveries
German inventions and discoveries are ideas, objects, processes or techniques invented, innovated or discovered, partially or entirely, in Germany or abroad by a person from Germany (that is, someone born in Germany – including to non-German parents – or born abroad with at least one German parent and who had the majority of their education or career in Germany). Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two.
German-born Albert Einstein, world-famous physicist
"What the world is today, good and bad, it owes to Gutenberg. Everything can be traced to this source, but we are bound to bring him homage, … for the bad that his colossal invention has brought about is overshadowed a thousand times by the good with which mankind has been favored."
American writer Mark Twain (1835−1910)[1]

Germany has been the home of many famous inventors, discoverers and engineers, including Carl von Linde, who developed the modern refrigerator;[2] Paul Nipkow, who laid the foundation of the television with his Nipkow disk;[3] Hans Geiger, the creator of the Geiger counter; and Konrad Zuse, who built the first fully automatic digital computer (Z3) and the first commercial digital computer (Z4).[4][5] Such German inventors, engineers and industrialists as Count Ferdinand von Zeppelin,[6] Otto Lilienthal, Gottlieb Daimler, Rudolf Diesel, Hugo Junkers and Karl Benz helped shape modern automotive and air transportation technology. Aerospace engineer Wernher von Braun developed the first space rocket at Peenemünde and later on was a prominent member of NASA and developed the Saturn V Moon rocket. Heinrich Rudolf Hertz's work in the domain of electromagnetic radiation was pivotal to the development of modern telecommunication.[7]
Albert Einstein introduced the special relativity and general relativity theories for light and gravity in 1905 and 1915 respectively. Along with Max Planck, he was instrumental in the introduction of quantum mechanics, in which Werner Heisenberg and Max Born later made major contributions.[8] Wilhelm Röntgen discovered X-rays.[9] Otto Hahn was a pioneer in the fields of radiochemistry and discovered nuclear fission, while Ferdinand Cohn and Robert Koch were founders of microbiology.
The movable-type printing press was invented by German blacksmith Johannes Gutenberg in the 15th century. In 1997, Time Life magazine picked Gutenberg's invention as the most important of the second millennium.[10] In 1998, the A&E Network ranked Gutenberg as the most influential person of the second millennium on their "Biographies of the Millennium" countdown.[10]
