Background: James Watt (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
Context: From an early age Watt was very interested in chemistry. In late 1786, while in Paris, he witnessed an experiment by Berthollet in which he reacted hydrochloric acid with manganese dioxide to produce chlorine. He had already found that an aqueous solution of chlorine could bleach textiles, and had published his findings, which aroused great interest among many potential rivals. When Watt returned to Britain, he began experiments along these lines with hopes of finding a commercially viable process. He discovered that a mixture of salt, manganese dioxide and sulphuric acid could produce chlorine, which Watt believed might be a cheaper method. He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties. He soon communicated these results to James McGrigor, his father-in-law, who was a bleacher in Glasgow. Otherwise he tried to keep his method a secret. With McGrigor and his wife Annie, he started to scale up the process, and in March 1788, McGrigor was able to bleach 1500 yards of cloth to his satisfaction. About this time Berthollet discovered the salt and sulphuric acid process, and published it so it became public knowledge. Many others began to experiment with improving the process, which still had many shortcomings, not the least of which was the problem of transporting the liquid product. Watt's rivals soon overtook him in developing the process, and he dropped out of the race. It was not until 1799, when Charles Tennant patented a process for producing solid bleaching powder (calcium hypochlorite) that it became a commercial success. By 1794 Watt had been chosen by Thomas Beddoes to manufacture apparatus to produce, clean and store gases for use in the new Pneumatic Institution at Hotwells in Bristol. Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the "factitious airs" had come to a dead end.
Question: was he able to keep it a secret?
Answer: Watt's rivals soon overtook him in developing the process, and he dropped out of the race.

Background: Hughes was born in Sydney, Australia, in 1938. His father and paternal grandfather were lawyers. Hughes's father, Geoffrey Forrest Hughes, was a pilot in the First World War, with later careers as a solicitor and company director. He died from lung cancer when Robert was aged 12.
Context: Hughes met his first wife, Danne Emerson, in London in 1967. Together they became involved in the counterculture of the 1960s, exploring drug use and sexual freedom. They divorced in 1981; she died of a brain tumor in 2003. Their son, Danton, Hughes's only child, was named after the French revolutionary Georges Danton. Danton Hughes, a sculptor, committed suicide in April 2001. He had been in a long term relationship with fashion designer Jenny Kee, who found his body on 15 April. Robert Hughes later wrote: "I miss Danton and always will, although we had been miserably estranged for years and the pain of his loss has been somewhat blunted by the passage of time". Hughes was married to his second wife, Victoria Whistler, a housewife from California, from 1981 until a divorce in 1996. In 1999, Hughes was involved in a near-fatal car accident south of Broome, Western Australia. He was returning from a fishing trip and driving on the wrong side of the road when he collided head on with another car carrying three occupants. He was trapped in the car for three hours before being airlifted to Perth in critical condition. Hughes was in a coma for five weeks after the crash. In a 2000 court hearing, Hughes's defence barrister alleged that the occupants of the other car had been transporting illicit drugs at the time of the accident and were at fault. In 2003 Hughes pleaded guilty to dangerous driving causing bodily harm and was fined A$2,500. He also allegedly described the crown prosecutor, Lloyd Rayney, as a "curry muncher", which resulted in a defamation action and out-of-court settlement. Hughes recounts the story of the accident and his recovery in the first chapter of his 2006 memoir Things I Didn't Know. In 2001, Hughes wed his third wife, the American artist and art director Doris Downes. "Apart from being a talented painter, she saved my life, my emotional stability, such as it is", he said.
Question: What year did they get married?
Answer: the 1960s,

Background: Fairport Convention are a British folk rock band. Formed in 1967, they are widely regarded as a key group in the English folk rock movement. Their seminal album Liege & Lief is considered to have launched the British folk rock movement, which provided a distinctively English identity to rock music and helped awaken much wider interest in traditional music in general. The band have drawn heavily on the Child Ballads, songs of the British Isles from the later medieval period until the 19th century.
Context: In 1998, Dave Mattacks moved to the USA and Gerry Conway took over on drums and percussion. Fairport produced two more studio albums for Woodworm Records: The Wood and the Wire (2000) and XXXV (2002). Then for Over the Next Hill (2004) they established a new label: Matty Grooves Records. In this period the band toured extensively in the UK, Europe, Australasia, Europe, the USA and Canada, and staged a major fund raiser for Dave Swarbrick at the Birmingham Symphony Hall. In 1998, members of the band began their association with the Breton musician Alan Simon. Working in collaboration with numerous others, members of Fairport (predominantly Nicol and Leslie) have performed in and participated in the recordings of all Simon's rock operas, including the Excalibur trilogy (1998, 2007, 2010) and Anne de Bretagne (2008). 2007 was their fortieth anniversary year and they celebrated by releasing a new album, Sense of Occasion. They performed the whole of the Liege & Lief album live at Cropredy, since 2004 renamed Fairport's Cropredy Convention, featuring the 1969 line-up of Dave Swarbrick, Ashley Hutchings, Dave Mattacks, Simon Nicol and Richard Thompson, with singer-songwriter Chris While taking the place of Sandy Denny. Footage of the festival, although not the Liege and Lief performance, was released as part of a celebratory DVD. The band's first official YouTube video appeared in April 2008. Edited from footage shot for the DVD, the nine-minute mini-documentary includes interviews with Lulu, Jools Holland, Seth Lakeman, Mike Harding, Geoff Hughes and Frank Skinner. In 2011, the band released a new studio album Festival Bell, the first new album in four years. This was followed in 2012 by Babbacombe Lee Live Again recorded live during the 2011 tour revisiting the Babbacombe Lee album first issued in 1971. In 2012, the band also released By Popular Request, a reworking in the studio of a number of the most popular songs in the band's repertoire (as determined by a mysterious consultation and voting process conducted by the band with its fans). In January 2015, four years after their previous studio album of original material (Festival Bell), Fairport Convention released a new one entitled Myths and Heroes.
Question: what have they been up to anything that stands out?
Answer:
2007 was their fortieth anniversary year and they celebrated by releasing a new album, Sense of Occasion.
