Here are the protagonists of the history of electrical engineering
Charles-Augustin de Coulomb (Angoulême, 14 giugno 1736 – Parigi, 23 agosto 1806) was a French military engineer and physicist. He is best known as the eponymous discoverer of what is now called Coulomb's law, the description of the electrostatic force of attraction and repulsion, though he also did important work on friction. The SI unit of electric charge, the coulomb, was named in his honor in 1908.
was a Russian physicist. He is most noted for formulating Lenz's law in electrodynamics in 1834. Lenz had begun studying electromagnetism in 1831. Besides the law named in his honor, Lenz also independently discovered Joule's law in 1842; to honor his efforts on the problem, it is also given the name the "Joule–Lenz law," named also for James Prescott Joule.
In 1902, he was awarded the Nobel Prize in Physics together with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect.
He also derived the transformation equations that were later used by Albert Einstein to describe space and time.
