September 22nd in stamps Michael Faraday, Queen Victoria, Alexander Potebnja

Here are some events that happened on September 22nd. It could be an event or a person that died or was born on that day


1791 Born: Michael Faraday, English physicist and chemist (d. 1867)

Michael Faraday (22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.

Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He similarly discovered the principles of electromagnetic induction and diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology.

As a chemist, Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as "anode", "cathode", "electrode" and "ion". Faraday ultimately became the first and foremost Fullerian Professor of Chemistry at the Royal Institution, a lifetime position.

Faraday was an excellent experimentalist who conveyed his ideas in clear and simple language; his mathematical abilities, however, did not extend as far as trigonometry and were limited to the simplest algebra. James Clerk Maxwell took the work of Faraday and others and summarized it in a set of equations which is accepted as the basis of all modern theories of electromagnetic phenomena. On Faraday's uses of lines of force, Maxwell wrote that they show Faraday "to have been in reality a mathematician of a very high order – one from whom the mathematicians of the future may derive valuable and fertile methods." The SI unit of capacitance is named in his honour: the farad.

Albert Einstein kept a picture of Faraday on his study wall, alongside pictures of Isaac Newton and James Clerk Maxwell. Physicist Ernest Rutherford stated, "When we consider the magnitude and extent of his discoveries and their influence on the progress of science and of industry, there is no honour too great to pay to the memory of Faraday, one of the greatest scientific discoverers of all time."

1835 Born: Alexander Potebnja, Ukrainian linguist and philosopher (d. 1891)

Alexander Potebnja (Russian: Алекса́ндр Афана́сьевич Потебня́; Ukrainian: Олекса́ндр Опана́сович Потебня́) was a Russian Imperial and Ukrainian linguist, philosopher and panslavist, who was a professor of linguistics at the Imperial University of Kharkov. He is well known as a specialist in the evolution of Russian phonetics.

He constructed a theory of language and consciousness that later influenced the thinking of his countryman the Psychologist Lev Vygotsky. His main work was Language and Thought (Russian: Мысль и язык) (1862). He also publisched a number of works on Russian Grammar, on the History of the Sounds in the Russian Language and on Slavic folk poetry, furthermore he translated a short fragment of Homer's Odyssey into Ukrainian. Potebnja was a corresponding member of the St. Petersburg Academy of Sciences, the foremost academic institution in the Russian Empire.

1896 – Queen Victoria surpasses her grandfather King George III as the longest reigning monarch in British history.

Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. She adopted the additional title of Empress of India on 1 May 1876. Known as the Victorian era, her reign of 63 years and seven months was longer than that of any of her predecessors. It was a period of industrial, cultural, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire.

Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld. After both the Duke and his father died in 1820, she was raised under close supervision by her mother and her comptroller, John Conroy. She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue. Though a constitutional monarch, privately, Victoria attempted to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.

Victoria married her cousin Prince Albert of Saxe-Coburg and Gotha in 1840. Their children married into royal and noble families across the continent, earning Victoria the sobriquet "the grandmother of Europe" and spreading haemophilia in European royalty. After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, republicanism in the United Kingdom temporarily gained strength, but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration. She died on the Isle of Wight in 1901. The last British monarch of the House of Hanover, she was succeeded by her son Edward VII of the House of Saxe-Coburg and Gotha.
