Henry Richmond Droop
Henry Richmond Droop (12 September 1832 – 21 March 1884) was an English mathematician. He devised the Droop quota used in the Single Transferable Vote. He also may have been the first to write down what later became known as Duverger's Law, in 1869. He married Clara Baily (ca. 1841 – 7 September 1921) on 17 August 1872 and was the father of archaeologist John Percival Droop (1882–1963).

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Droop Quota
The Droop quota is the quota most commonly used in elections held under the single transferable vote (STV) system. It is also sometimes used in elections held under the largest remainder method of party-list proportional representation (list PR). In an STV election the quota is the minimum number of votes a candidate must receive in order to be elected. Any votes a candidate receives above the quota are transferred to another candidate. The Droop quota was devised in 1868 by the English lawyer and mathematician Henry Richmond Droop (1831–1884) as a replacement for the earlier Hare quota. Today the Droop quota is used in almost all STV elections, including the forms of STV used in India, the Republic of Ireland, Northern Ireland, Malta and Australia, among other places, and is also used to allocate seats via the largest remainder model in South Africa. The Droop quota is very similar to the simpler Hagenbach-Bischoff quota, which is also sometimes loosely referred to as the 'Dro ...

Single Transferable Vote
Single transferable vote (STV) is a multi-winner electoral system in which voters cast a single vote in the form of a ranked-choice ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternate preferences if their preferred candidate is eliminated, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another. Under STV, no one party or voting bloc can take all the seats in a district unless the number of seats in the district is very small or almost all the votes cast are cast for one party's candidates (which is seldom the case). This makes it different from other district voting systems. In majoritarian/plurality systems such as first-past-the-post (FPTP), instant-runoff voting (IRV; also known as the alternative vote), block voting, and ranked-vote ...

John Percival Droop
John Percival Droop (4 October 1882 – 26 September 1963, in Vence, France) was a British classical archaeologist of Dutch descent. After attending Marlborough College and Trinity College, Cambridge, Droop became a student of the British School at Athens, where he excavated at Sparta, in Thessaly, on Milos and on Crete. He later became a full member of the BSA. In 1911, Droop joined T. Eric Peet's Egypt Exploration Fund at Abydos, where he and Peet developed a system for dating pre-dynastic Egyptian ceramics. During the First World War, Droop worked for the Admiralty, and remained in post until 1921, when he was appointed the Charles W. Jones Professor of Classical Archaeology in the University of Liverpool, a position he held until 1948. He excavated widely: at Chester, Bainbridge and Lancaster in Britain, and at Niebla in Spain. He edited the scholarly journal ''Annals of Archaeology and Anthropology'' from 1937 until 1948. Droop gives his name to an Ancient Greek ...

Voting Matters
''Voting matters'' was a peer-reviewed academic journal whose purpose is "To advance the understanding of preferential voting systems".

The highest-ranking editor of a publication may also be titled editor, managing ... (1994–2010) was British mathematician and computer scientist Brian Wichmann, followed by Nicolaus Tideman. The majority of ''Voting matters'' papers dealt with the single transferable vote (STV) preferential voting system. The journal has also republished several seminal papers on STV by Thomas Hare (political scientist), Thomas Hare, Henry Richmond Droop, and Brian Meek. Other papers, such as "Four Condorce ...

At the time, it was known as the Year of the Consulship of Aurelius and Victorinus (or, less frequently, year 936 ''Ab urbe condita'').
