Michael Faraday

Michael Faraday, FRS (22 September 1791 – 25 August 1867) was an English chemist and physicist(or natural philosopher, in the terminology of the time) who contributed to the fields of electromagnetism and electrochemistry.

Faraday studied the magnetic field around a conductor carrying a DC electric current. While conducting these studies, Faraday established the basis for the electromagnetic field concept in physics, subsequently enlarged upon by James Maxwell. He similarly discovered electromagnetic induction,diamagnetism, and laws of electrolysis. He established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became viable for use in technology.

As a chemist, Michael Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularized terminology such as anode, cathode, electrode, and ion.

Although Faraday received little formal education and knew little of higher mathematics, such as calculus, he was one of the most influential scientists in history. Historians of science refer to him as the best experimentalist in the history of science. The SI unit of capacitance, the farad, is named after him, as is the Faraday constant, the charge on a mole of electrons (about 96,485 coulombs). Faraday’s law of induction states that magnetic flux changing in time creates a proportional electromotive force.

Faraday was the first and foremost Fullerian Professor of Chemistry at the Royal Institution of Great Britain, a position to which he was appointed for life.

Albert Einstein kept a photograph of Faraday on his study wall alongside pictures of Isaac Newton and James Clerk Maxwell.

Faraday was highly religious; he was a member of the Sandemanian Church, a Christian sect founded in 1730 that demanded total faith and commitment. Biographers have noted that “a strong sense of the unity of God and nature pervaded Faraday’s life and work.”

When asked by the British government to advise on the production of chemical weapons for use in the Crimean War (1853–1856), Faraday refused to participate citing ethical reasons.

Faraday died at his house at Hampton Court on 25 August 1867. He had previously turned down burial in Westminster Abbey, but he has a memorial plaque there, near Isaac Newton’s tomb. Faraday was interred in the dissenters’ (non-Anglican) section of Highgate Cemetery.

    Faraday, bless him, is not in line for shooting down, so everyone can relax. Did you know that he was a poor boy who received only the rudiments of education; just the three Rs? He was the son of a blacksmith from Cumberland and this is perhaps how he learned about practical techniques.
    Apprenticed to a bookbinder and bookseller, he found the work limiting, but it gave him a marvellous opportunity to read widely, and educate himself. He was given tickets to Humphrey Davy’s Royal Institution lectures by a generous customer of the bookshop who recognised Faraday’s studious qualities.
    Faraday took detailed notes of the lectures and eventually bound them into a book. Wanting to get into science as a career, he wrote to Davy for for help, and enclosed the book of lecture notes as an indication of the seriousness of his purpose. He received a very courteous and positive reply from Davy, given that that latter was a professor replying to an ordinary member of the public.
    Luck, that vital ingredient was on Faraday’s side. The current RI lab technician had got drunk, got into a fight and had his arm broken. Davy fired him and took on Faraday as a technician in his place. Davy remained at the R I for the rest of his life eventually taking over from Davy as Professor.
    Faraday ought to be the patron saint of poor boys, who seize with both hands, what small opportunities come their way. In addition, perhaps, he should be the patron saint of lab technicians, as an encouragement to them to aspire to more advanced work. Back in 1953, when the world was young, I worked as a technician in a London hospital. One of the older members of the research team, a Scottish doctor, encouraged me and explained that many years ago he had been a technician and had worked his way up. I calculate that this would have been during or just after WWI.
    Faraday was a very accomplished lecturer and he also wrote very well. In conclusion, the evidence points to Faraday being a nice man. He was quiet and courteous, and although he and his wife Sarah had no children Faraday was popular and greatly loved by his nieces and nephews.

    Wow, I got the feeling you might even like him Alfy. Is this a first?
