Getting to know the past and its history helps us appreciate the present and look forward to the future. So many people have made our lives easier today. They spent their time finding ideas to make life convenient and made inventions to satisfy their thirst for discovery which later on became beneficial for us. For that, we owe them gratitude for making such amazing work.
Today, we are exposed to electronic devices anywhere we go. Our appliances, TVs, computers and phones are all electronics or contain them. Electronics have also greatly benefited the fields of automobiles, health care, technology, farming and more. To better appreciate the history of electronics, let’s get to know some of the talented people behind the inventions that made a huge difference in our lives today.
1. Luigi Galvani (1737-1798) – showed the presence of electricity in frogs on 1791.
2. Charles Coulomb (1737-1806) – developed Coulomb’s law of electro-static charges in 1799.
3. Allesandro Volta (1745-1827) – Invented the battery in 1799.
4. George Simon Ohm (1789-1854) – Ohms law and unit of resistance is named before him.
5. Hans Christian Oersted (1777-1852) – Famous for electromagnetism and creating aluminum in 1820.
6. Karl Friedrich Gauss (1777-1855) – Contributed to algebra, statistics, astronomy, analysis and electrostatics.
7. Michael Faraday (1791-1867) – Discovered the Oersted and showed how the electromagnetic induction works.
8. Joseph Henry (1799-1878) – An American scientist who single-handedly developed electromagnetic induction during 1831, just a year before Faraday made the discovery.
9. Wilhelm Eduard Weber (1804-1891) – Studied terrestrial magnetism and invented the electromagnetic telegraph in 1833.
10. Andre Marie Ampere (1775-1836) – Studied electric currents effects and created solenoids. “Ampere,” the SI unit of electric current carries his name.
11. James Clerk Maxwell (1831-1879) – Formulated the electromagnetic filed equations and electromagnetic theory of light in 1864.
12. Gustav Robert Kirchhoff (1824-1887) – He invented the Kirchoff’s law.
13. James Prescott Joule (1818-1889) – He discovered the law of conservation of energy and the joule unit of energy was named after him and. With Lord Kelvin, Joule developed the temperature scale.
14. Henrich Rudolph Hertz (1857-1894) – First to demonstrate the effect of photo-electric and in honor of him, the unit of frequency was named after him.
15. Nikola Tesla (1856-1943) – The Tesla induction motor, Tesla coil and alternating current were invented by him. The unit of magnetic field density is named after him.
16. Thomas Alva Edison (1847-1932) – Invented the motion picture camera, photograph and practical electric bulb.
17. Edwin Howard Armstrong (1890-1954) – An American inventor and electrical engineer, he developed regenerative feedback and the electronic oscillator. He also invented the super-heterodyne radio in 1918 and FM radio in 1934.
18. Lee De Forest (1873-1961) – An American inventor who developed the first ever triode vacuum tube. He called it the Audion tube and he is also recognized as the father of radio.
19. Walter Schottky (1886-1976) – A German physicist that explained random electron noise on thermionic tubes and produced the multiple grid vacuum tube.
