input: William Rufus inherited the Anglo-Norman settlement detailed in the Domesday Book, a survey undertaken at his father's command, essentially for the purposes of taxation, which was an example of the control of the English monarchy. If he was less effective than his father in containing the Norman lords' propensity for rebellion and violence, through charisma, or political skills, he was forceful in overcoming the consequences. In 1095, Robert de Mowbray, the earl of Northumbria, refused to attend the Curia Regis, the thrice-annual court where the King announced his governmental decisions to the great lords. William led an army against Robert and defeated him. Robert was dispossessed and imprisoned, and another noble, William of Eu, accused of treachery, was blinded and castrated.  In external affairs, William had some successes. In 1091 he repulsed an invasion by King Malcolm III of Scotland, forcing Malcolm to pay homage. In 1092 he built Carlisle Castle, taking control of Cumberland and Westmorland, which had previously been claimed by the Scots. Subsequently, the two kings quarrelled over Malcolm's possessions in England, and Malcolm again invaded, ravaging Northumbria. At the Battle of Alnwick, on 13 November 1093, Malcolm was ambushed by Norman forces led by Robert de Mowbray. Malcolm and his son Edward were killed and Malcolm III's brother Donald seized the throne. William supported Malcolm's son Duncan II, who held power for a short time, and then another of Malcolm's sons, Edgar. Edgar conquered Lothian in 1094 and eventually removed Donald in 1097 with William's aid in a campaign led by Edgar AEtheling. Edgar recognised William's authority over Lothian and attended William's court.  William made two forays into Wales in 1097. Nothing decisive was achieved, but a series of castles was constructed as a marchland defensive barrier.  In 1096, William's brother Robert Curthose joined the First Crusade. He needed money to fund this venture and pledged his Duchy of Normandy to William in return for a payment of 10,000 marks--a sum equalling about a quarter of William's annual revenue. In a display of the effectiveness of English taxation, William raised the money by levying a special, heavy, and much-resented tax upon the whole of England. William then ruled Normandy as regent in Robert's absence. Robert did not return until September 1100, one month after William's death.  As regent for his brother Robert in Normandy, William campaigned in France from 1097 to 1099. He secured northern Maine but failed to seize the French-controlled part of the Vexin region. According to William of Malmesbury he was planning to invade Aquitaine at the time of his death.

input: After leaving the Navy, Attenborough took a position editing children's science textbooks for a publishing company. He soon became disillusioned with the work and in 1950 applied for a job as a radio talk producer with the BBC. Although he was rejected for this job, his CV later attracted the interest of Mary Adams, head of the Talks (factual broadcasting) department of the BBC's fledgling television service.  Attenborough, like most Britons at that time, did not own a television, and he had seen only one programme in his life. However, he accepted Adams' offer of a three-month training course, and in 1952 he joined the BBC full-time. Initially discouraged from appearing on camera because Adams thought his teeth were too big, he became a producer for the Talks department, which handled all non-fiction broadcasts. His early projects included the quiz show Animal, Vegetable, Mineral? and Song Hunter, a series about folk music presented by Alan Lomax.  Attenborough's association with natural history programmes began when he produced and presented the three-part series Animal Patterns. The studio-bound programme featured animals from London Zoo, with the naturalist Julian Huxley discussing their use of camouflage, aposematism and courtship displays. Through this programme, Attenborough met Jack Lester, the curator of the zoo's reptile house, and they decided to make a series about an animal-collecting expedition. The result was Zoo Quest, first broadcast in 1954, where Attenborough became the presenter at short notice due to Lester being taken ill.  In 1957, the BBC Natural History Unit was formally established in Bristol. Attenborough was asked to join it, but declined, not wishing to move from London where he and his young family were settled. Instead, he formed his own department, the Travel and Exploration Unit, which allowed him to continue to front Zoo Quest as well as produce other documentaries, notably the Travellers' Tales and Adventure series.  In the early 1960s, Attenborough resigned from the permanent staff of the BBC to study for a postgraduate degree in social anthropology at the London School of Economics, interweaving his study with further filming. However, he accepted an invitation to return to the BBC as controller of BBC Two before he could finish the degree.
