Short Summary
Michael Faraday was an eminent 19th-century British scientist known for his pioneering discoveries in electromagnetism and electrochemistry. His most notable contributions include the principles underlying electromagnetic induction, diamagnetism, and electrolysis. Despite having minimal formal education, Faraday became one of the most influential scientists in history, revolutionizing the understanding of electricity and magnetism. His work laid the foundation for many modern technologies, and he is celebrated for his ability to communicate complex scientific ideas to the public.
Early Life & Education
Born on September 22, 1791, in Newington Butts, England, Michael Faraday was the son of a blacksmith. His family was not wealthy, and his formal education was limited. At the age of 14, he was apprenticed to a local bookbinder and bookseller, George Riebau. It was during this apprenticeship that Faraday developed a keen interest in science by reading books on the subject, including Isaac Watts' "The Improvement of the Mind" and Jane Marcet's "Conversations on Chemistry." His early passion for science led him to attend lectures by the renowned chemist Humphry Davy, which significantly influenced his future career in science.
Career Highlights
Faraday's career began in earnest when he joined the Royal Institution of Great Britain as an assistant to Humphry Davy in 1813. He quickly rose through the ranks, becoming a key figure at the Institution. In 1821, he discovered electromagnetic rotation, a fundamental principle behind the electric motor. His groundbreaking work on electromagnetic induction in 1831 provided the working principle for the electric transformer and generator. Faraday's innovative experiments in electrochemistry and his establishment of the laws of electrolysis further solidified his reputation as a leading scientist of his time.
