Alexander Crichton Mitchell
Alexander Crichton Mitchell FRSE (1 July 1864 – 15 April 1952), named in some sources as Arthur Crichton Mitchell, was a Scottish physicist with a special interest in geomagnetics who worked for many years in India as a professor and head of a meteorological observatory before returning to Scotland. He then worked with the Royal Navy to devise a system, known as an anti-submarine indicator loop, for detecting submarines by detecting currents induced in a loop of wire on the sea floor. Early life Mitchell was born in Leith on 1 July 1864 to James Mitchell and Isabella Mitchell née Crichton. He studied physics at Edinburgh University and graduated with a Bachelor of Science. He was elected Fellow of the Royal Society of Edinburgh in 1889. His proposers were Peter Guthrie Tait, Alexander Crum Brown, George Chrystal, and Sir Thomas Clark. He was elected a Fellow of the Scottish Meteorological Society in 1891. India In 1890, he went to Trivandrum, in India, where he taught physic ...

Edinburgh
Edinburgh ( ; gd, Dùn Èideann ) is the capital city of Scotland and one of its 32 council areas. Historically part of the county of Midlothian (interchangeably Edinburghshire before 1921), it is located in Lothian on the southern shore of the Firth of Forth. Edinburgh is Scotland's second-most populous city, after Glasgow, and the seventh-most populous city in the United Kingdom. Recognised as the capital of Scotland since at least the 15th century, Edinburgh is the seat of the Scottish Government, the Scottish Parliament and the highest courts in Scotland. The city's Palace of Holyroodhouse is the official residence of the British monarchy in Scotland. The city has long been a centre of education, particularly in the fields of medicine, Scottish law, literature, philosophy, the sciences, and engineering. It is the second-largest financial centre in the United Kingdom, and the city's historical and cultural attractions have made it the UK's second-most visited tourist d ...

John Caldecott
John Caldecott (16 September 1801 – 16 December 1849, Trivandrum) was an East India Company commercial agent, meteorologist and astronomer who worked in the court of the Raja of Travancore at the Trivandrum Observatory. Caldecott was born in Finsbury in London where his father, also John, and mother Susannah lived. He was christened on 1 November 1801 at St Luke's Church. John Caldecott (junior) went to India in 1820 on the ''Mulgrave Castle'' and reached Bombay in May 1821. He worked at Apollo Cotton as an assistant to Daniel West who was a family friend. A relative, William West had an interest in telescopes and microscopes as an evening amusement and this sparked off a scientific interest in John Caldecott. In 1832 he was posted as a commercial agent at the Indian port of Allepey (now Alappuzha) and he saw the need for an astronomical observatory there. This idea was aired in 1836, supported by the Resident Colonel James Stuart Fraser and approved by Raja Swathi Thirunal Ra ...

Scientists From Edinburgh
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

1952 Deaths
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita'').

Keith Medal
The Keith Medal was a prize awarded by the Royal Society of Edinburgh, Scotland's national academy, for a scientific paper published in the society's scientific journals, preference being given to a paper containing a discovery, either in mathematics or earth sciences. The Medal was inaugurated in 1827 as a result of a gift from Alexander Keith of Dunnottar, the first Treasurer of the Society. It was awarded quadrennially, alternately for a paper published in: Proceedings A (Mathematics) or Transactions (Earth and Environmental Sciences). The medal bears the head of John Napier of Merchiston. The medal is no longer awarded.

Geneva University
The University of Geneva (French: ''Université de Genève'') is a public research university located in Geneva, Switzerland. It was founded in 1559 by John Calvin as a theological seminary. It remained focused on theology until the 17th century, when it became a center for enlightenment scholarship. Today, it is the third largest university in Switzerland by number of students. In 1873, it dropped its religious affiliations and became officially secular. In 2009, the University of Geneva celebrated the 450th anniversary of its founding. Almost 40% of the students come from foreign countries. The university holds and actively pursues teaching, research, and community service as its primary objectives.

Alfred Ewing
Sir James Alfred Ewing MInstitCE (27 March 1855 − 7 January 1935) was a Scottish physicist and engineer, best known for his work on the magnetic properties of metals and, in particular, for his discovery of, and coinage of the word, ''hysteresis''. It was said of Ewing that he was 'Careful at all times of his appearance, his suits were mostly grey, added to which he generally wore – whatever the fashion – a white piqué stripe to his waistcoat, a mauve shirt, a white butterfly collar and a dark blue bow tie with white spots.' He was regarded as brilliant and successful, but was conscious of his dignity and position. On appointment to head the newly created Admiralty codebreaking department, the Director of Naval Intelligence, Henry Oliver, described him as 'too distinguished a man to be placed officially under the orders of the Director of Intelligence or Chief of Staff'. His first wife, Annie, was an American, a great great niece of George Washington. Life Early lif ...

Eskdalemuir Observatory
The Eskdalemuir Observatory is a UK national environmental observatory located near Eskdalemuir, Dumfries and Galloway, Scotland. Built in 1904, its remote location was chosen to minimise electrical interference with geomagnetic instruments, which were relocated here from Kew Observatory in London in 1908 after the spread of electric tramcars led to excessive electromagnetic interference there. The distinguished meteorologist and mathematician Lewis Fry Richardson served as Superintendent at the Observatory between 1913 and 1918. Purpose The observatory is situated in the valley of the White Esk river at an altitude of 242m, and so represents the climate of highland in northern Great Britain. It currently monitors: *Meteorological parameters *Solar radiation *Atmospheric pollution *The UK Geomagnetic field *Seismological activity The observatory is managed by the British Geological Survey and the UK Met Office. Seismic measurements The area has a low background of seism ...
