input: Burton died in Trieste early on the morning of 20 October 1890 of a heart attack. His wife Isabel persuaded a priest to perform the last rites, although Burton was not a Catholic and this action later caused a rift between Isabel and some of Burton's friends. It has been suggested that the death occurred very late on 19 October and that Burton was already dead by the time the last rites were administered. On his religious views, Burton called himself an atheist, stating he was raised in the Church of England which he said was "officially (his) church". Isabel never recovered from the loss. After his death she burned many of her husband's papers, including journals and a planned new translation of The Perfumed Garden to be called The Scented Garden, for which she had been offered six thousand guineas and which she regarded as his "magnum opus". She believed she was acting to protect her husband's reputation, and that she had been instructed to burn the manuscript of The Scented Garden by his spirit, but her actions have been widely condemned. Isabel wrote a biography in praise of her husband. The couple are buried in a remarkable tomb in the shape of a Bedouin tent, designed by Isabel, in the cemetery of St Mary Magdalen Roman Catholic Church Mortlake in southwest London. The coffins of Sir Richard and Lady Burton can be seen through a window at the rear of the tent, which can be accessed via a short fixed ladder. Next to the lady chapel in the church there is a memorial stained-glass window to Burton, also erected by Isabel; it depicts Burton as a mediaeval knight. Burton's personal effects and a collection of paintings, photographs and objects relating to him are in the Burton Collection at Orleans House Gallery, Twickenham.

input: His father had taken him to a league game at Goodison Park when he was eight years old. It was a dream come true for Dean when Everton secretary Thomas H. McIntosh arranged to meet him at the Woodside Hotel in 1925. Dean was so excited that he ran the 2.5 miles (4.0 km) distance from his home in north Birkenhead to the riverside to meet him. He signed for Everton in March 1925 having just turned 18. He later revealed that he expected a PS300 signing fee to be given to his parents when he transferred to Everton. They received only PS30, and Tranmere Rovers manager Bert Cooke told him "that's all the League will allow". Dean appealed to John McKenna, chairman of the Football Association, but was told "I'm afraid you've signed, and that's it." Dean signed for Everton for PS3,000, then a record fee received for Tranmere Rovers. He made an immediate impact, scoring 32 goals in his first full season. A motorcycling accident at Holywell, North Wales in summer 1926 left Dean with a fractured skull and jaw, and doctors were unsure whether he would be able to play again. In his next game for Everton he scored using his head, leading Evertonians to joke that the doctor left a metal plate in Dean's head. Dean's greatest point of note is he is still the only player in English football score 60 league goals in one season (1927-28). At that season's end he was 21 years old. Middlesbrough's George Camsell, who holds the highest goals-to-games ratio for England, had scored 59 league goals the previous season. In that 1927-28 season Everton won the First Division title. When they were relegated to Second Division in 1930 Dean stayed with them. The club went on to immediately win the Second Division in 1931 followed by the First Division again in 1932. They then immediately won the FA Cup in 1933 (in which he scored in the final) - a sequence unmatched since. In December 1933, Dean issued a public appeal to have stolen goods returned to him. The Times issued a statement: "Dixie Dean, the Everton and England forward appeals to the thief who robbed him of an international cap and presentation clock to return them. His house in Caldy Road, Walton, Liverpool was entered in his absence over Christmas, and the thief left behind gold watches and jewelry (sic)." By then, Dean was captain of the side. However, the harsh physical demands of the game (as it was played then) took their toll and he was dropped from the first team in 1937.

input: At the 1904 Louisiana Purchase Exposition, Valdemar Poulsen had presented a paper on an arc transmitter, which unlike the discontinuous pulses produced by spark transmitters, created steady "continuous wave" signals that could be used for amplitude modulated (AM) audio transmissions. Although Poulsen had patented his invention, de Forest claimed to have come up with a variation that allowed him to avoid infringing on Poulsen's work. Using his "sparkless" arc transmitter, de Forest first transmitted audio across a lab room on December 31, 1906, and by February was making experimental transmissions, including music produced by Thaddeus Cahill's telharmonium, that were heard throughout the city. On July 18, 1907, de Forest made the first ship-to-shore transmissions by radiotelephone -- race reports for the Annual Inter-Lakes Yachting Association (I-LYA) Regatta held on Lake Erie -- which were sent from the steam yacht Thelma to his assistant, Frank E. Butler, located in the Fox's Dock Pavilion on South Bass Island. De Forest also interested the U.S. Navy in his radiotelephone, which placed a rush order to have 26 arc sets installed for its Great White Fleet around-the-world voyage that began in late 1907. However, at the conclusion of the circumnavigation the sets were declared to be too unreliable to meet the Navy's needs and removed. The company set up a network of radiotelephone stations along the Atlantic coast and the Great Lakes, for coastal ship navigation. However, the installations proved unprofitable, and by 1911 the parent company and its subsidiaries were on the brink of bankruptcy.
