Arthur Wallis Exell00
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a mat ...

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and language. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of t ...

Caprivi Strip
The Caprivi Strip, also known simply as Caprivi, is a geographic salient protruding from the northeastern corner of Namibia. It is surrounded by Botswana to the south and Angola and Zambia to the north. Namibia, Botswana and Zambia meet at a single point at the eastern tip of the Strip, which also comes within of Zimbabwe thus nearly forming a quadripoint. Botswana and Zambia share a border at the crossing of Kazungula. The territory was acquired by then-German South West Africa in order to provide access to the Zambezi River and consequently a route to the east coast of the continent and German East Africa. The route was later found not to be navigable because about east of the Caprivi Strip is Victoria Falls, one of the world's largest waterfalls. Within Namibia, the Strip is divided administratively between Kavango East and Zambezi regions. It is crossed by the Okavango River. The Cuando River forms part of its border with Botswana, and the Zambezi River forms a part of it ...

Federation Of Rhodesia And Nyasaland
The Federation of Rhodesia and Nyasaland, also known as the Central African Federation or CAF, was a colonial federation that consisted of three southern African territories: the Self-governing colony, self-governing British colony of Southern Rhodesia and the British protectorates of Northern Rhodesia and Nyasaland. It existed between 1953 and 1963. The Federation was established on 1 August 1953, with a Governor-General of the Federation of Rhodesia and Nyasaland, Governor-General as the Queen's representative at the centre. The constitutional status of the three territories a self-governing Colony and two Protectorates was not affected, though certain enactments applied to the Federation as a whole as if it were part of Her Majesty's dominions and a Colony. A novel feature was the African Affairs Board, set up to safeguard the interests of Africans and endowed with statutory powers for that purpose, particularly in regard to discriminatory legislation. The economic adv ...

Zambesi River
The Zambezi River (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers , slightly less than half of the Nile's. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. The Zambezi's most noted feature is Victoria Falls. Its other falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls near Sioma in western Zambia. The two main sources of hydroelectric power on the river are the Kariba Dam, which provides power to Zambia and Zimbabwe, and the Cahora Bassa Dam in Mozambique, which provides power to Mozambique and South Africa. Additionally, two smaller power stations are along the Zambezi Rive ...

Flora Zambesiaca
''Flora Zambesiaca'' is an ongoing botanical project aimed at achieving a full account of the flowering plants and ferns of the Zambezi River basin covering Zambia, Malawi, Mozambique, Zimbabwe, Botswana and the Caprivi Strip, and is published by the Royal Botanic Gardens, Kew. The work is published in parts or whole volumes as and when the relevant families are completed, and is currently (2012) over the halfway mark. Some 24 500 plant species have been described so far. The majority of the line illustration plates in the first volume were by Miss L. M. Ripley and Miss G. W. Dalby. The ''Flora Zambesiaca'' project was set in motion in 1950 by Arthur Wallis Exell when he returned to the British Museum from his wartime activities with the Government Communications Headquarters at Bletchley Park Bletchley Park is an English country house and estate in Bletchley, Milton Keynes ( Buckinghamshire) that became the principal centre of Allied code-breaking during the Second World ...

Bletchley Park
Bletchley Park is an English country house and estate in Bletchley, Milton Keynes ( Buckinghamshire) that became the principal centre of Allied code-breaking during the Second World War. The mansion was constructed during the years following 1883 for the financier and politician Sir Herbert Leon in the Victorian Gothic, Tudor, and Dutch Baroque styles, on the site of older buildings of the same name. During World War II, the estate housed the Government Code and Cypher School (GC&CS), which regularly penetrated the secret communications of the Axis Powersmost importantly the German Enigma and Lorenz ciphers. The GC&CS team of codebreakers included Alan Turing, Gordon Welchman, Hugh Alexander, Bill Tutte, and Stuart Milner-Barry. The nature of the work at Bletchley remained secret until many years after the war. According to the official historian of British Intelligence, the "Ultra" intelligence produced at Bletchley shortened the war by two to four years, and without it th ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ...
