Credit goes to Johannes Gutenberg for transforming book-making from manuscripts to the printed form as he introduced the movable-type printing press in the 15th century. The German printer and publisher’s invention contributed to mass communication during the Renaissance. He was not successful in his business and was exiled during the later years of his life. He was also a goldsmith.
Wilhelm Rontgen was a German physicist and mechanical engineer. He is best remembered for producing and detecting X-rays for which he was honored with the first Nobel Prize in Physics in 1901. His discovery of X-rays remains one of the greatest achievements in the field of medical science.
Gottlieb Daimler was a German engineer, industrialist, and industrial designer. A pioneer of automobile development and internal combustion engines, Daimler is credited with inventing the liquid petroleum-fueled engine. In 1978, Gottlieb Daimler was inducted into the Automotive Hall of Fame.
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.
A descendant of Pennsylvania founder William Penn through his mother, Hermann von Helmholtz studied medicine, pushed by his father, in spite of being interested in the natural sciences. Best known for his law of conservation of energy, he coalesced the fields of medicine, physiology, math, and physics in his studies.
German electrical engineer Werner von Siemens is remembered as a pioneer of the telegraph industry. The founder of Siemens also inspired the name to the SI unit of electrical conductance. He was part of the Prussian army and had begun his chemistry experiments while in prison for a minor crime.
16 Hugo Junkers
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.
20 Hans Geiger
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.
23 Karl Drais
25 Hennig Brand
26 Felix Wankel
31 Ernst Ruska
Ernst Ruska was a German physicist whose work in electron optics earned him the prestigious Nobel Prize in Physics in 1986. His work led to the discovery of electron microscope, which plays a key role in the field of medical science. From 1957 to 1974, Ernst Ruska also worked at the Technical University of Berlin where he taught several students.
