John B. Goodenough is an American solid-state physicist and materials scientist. He is credited with developing the lithium-ion battery. In 2019, he became the oldest person to receive a Nobel Prize when he was honored with the prestigious award for his work on lithium-ion batteries. He is also a recipient of the Copley Medal and the National Medal of Science.
Karl Benz was a German engine designer, automotive engineer, and entrepreneur. He designed the Benz Patent Motorcar, for which he received a patent in 1886. He studied mechanical engineering at the University of Karlsruhe before venturing into developing motorcars. His Benz Patent Motorcar is widely regarded as the world's first production automobile.
Joseph Pilates was a German physical trainer. He is credited with developing and popularizing the Pilates method of physical training. Originally a bodybuilder and gymnast, Pilates studied the movements of animals, especially cats, and modeled his fitness training based on this. He was featured in a documentary movie titled A Movement of Movement.
The founder of the German engineering and technological MNC Bosch, Robert Bosch was born to a farmer in a south Germany village. He is also remembered as one of the first Germans to introduce 8-hour work days. He also invented the high-voltage spark plug and magneto for automobiles.
German anatomist and physician Gunther von Hagens is best known for inventing plastination, or a unique method of preserving human body tissue after death. He also started the Body Worlds exhibition, to display dissections, and later established permanent exhibitions. He has also been dragged into legal hassles for using corpses illegally.
German aeronautical engineer Otto Lilienthal became the first known person to use gliders for a successful flight. A mechanical engineer, he owned a shop and flight factory and developed gliders, with which he completed around 2,000 flights. Lilienthal, however, died after breaking his back in a glider crash.
Born to a German Jewish family, Ralph H. Baer and his family escaped to New York later. He went from working in a factory to becoming an engineer. While working at Sanders Associates, he developed the idea of playing games on TV and later created the first video game console.
German engineer and auto designer Wilhelm Maybach once earned the nickname The King of Designers. He collaborated with Gottlieb Daimler and formed Daimler-Motoren-Gesellschaft, eventually designing the first Mercedes automobiles. He and his son later started an aircraft engine company. In 1996, he was inducted into the Automotive Hall of Fame.
German chemist Justus von Liebig is best known for his research on organic compounds and his contribution to biochemistry and agriculture. The Copley Medal-winning scientist initially studied pharmacy but later switched to chemistry. As a professor, he stressed on laboratory-based teaching of chemistry and separating it from pharmacy, opposing traditional methods.
Though German-born American mathematician and engineer Charles Proteus Steinmetz suffered from a deformed back since childhood, he excelled in math, physics, and classical literature. His ideas on alternating current (AC) systems initiated the electrical era in the US. By the time he died, he had over 200 patents under his name.
German chemist Johann Wolfgang Döbereiner was born amid poverty but managed to get training as an apothecary. After his university education, he taught at the University of Jena. His discovery of the fact that certain chemical elements were similar later led to the development of the periodic law of chemistry.
Karl Ferdinand Braun was a German electrical engineer, inventor, and physicist. He made significant contributions to the development of radio and TV technology. In 1909, he jointly received the Nobel Prize in Physics with Guglielmo Marconi for their contribution to the development of wireless telegraphy. His work led to the later development of radar, smart antennas, and MIMO.
Otto von Guericke was a German inventor, scientist, and politician. He made several significant contributions to the development of the Scientific Revolution. He is also credited with inventing the first air pump which he used effectively to study the phenomenon of vacuum. His studies and observation helped reveal the fact that light unlike sound can travel through a vacuum.
Felix Hoffmann was a German chemist best remembered for re-synthesizing diamorphine, which was later popularized as heroin. Hoffmann is also known for synthesizing aspirin, although it is still unclear whether he synthesized it on his own or under the direction of Arthur Eichengrün. In 2002, Felix Hoffmann was inducted into the US National Inventors Hall of Fame.
Starting his career as a mechanic at age 12, Siegfried Marcus grew up to be one of the most legendary engineers and manufacturers of his time. His experimental creation, known as Marcus's second car, was the first automobile with a four-cycle engine and the first that used gasoline as fuel.
Apart from being an army officer and a physician, Hennig Brand was also an alchemist who was constantly looking for the mythical philosopher’s stone. His research led him to discover phosphorus by accident, which he kept a secret, though it was later formally discovered by Robert Boyle from England.
German-British inventor and electrical engineer, who revolutionized the steel-making and glass-making industries, is best remembered for using the Siemens-Martin process to create the regenerative furnace. His achievements earned him accolades such as the Albert Medal. He was a Fellow of The Royal Society and was knighted shortly before his death.
Nobel Prize-winning German physicist Gerd Binnig invented the scanning tunneling microscope, with fellow Nobel laureate Heinrich Rohrer. As a child, he devoted a lot of time to music, playing the violin and performing for an orchestra. He spent most of his scientific career with the IBM research team.
Oskar Barnack was a German photographer and inventor. He is credited with building a device, which would later become the first successful 35mm still-camera. Barnack developed the camera, which was named Leica, at the Leitz Company where he was working as an engineer. Oskar Barnack is also credited with creating news images, which he made with his 35 mm camera.
German chemist Christian Friedrich Schönbein is best remembered for his discovery of ozone and the fuel cell. He also discovered guncotton, or nitrocellulose, as a result of a kitchen accident. He was an apprentice at a chemical firm at 13 and grew up to teach at the at the University of Basel.
