Question: 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.

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: Charles Michael "Chuck" Schuldiner (May 13, 1967 - December 13, 2001) was an American singer, songwriter, and guitarist. He founded the pioneering band Death in 1983. Schuldiner is often referred to as "The Godfather of death metal", and his obituary in the January 5, 2002 issue of UK's Kerrang! magazine said that "Chuck Schuldiner was one of the most significant figures in the history of metal."

Schuldiner was born on May 13, 1967, on Long Island, New York to a Jewish father of Austrian descent and a mother from the American South, a convert to Judaism. Both of his parents were teachers. In 1968, his family moved to Florida.  Schuldiner was the youngest of three children: he had an older brother named Frank and an older sister named Bethann. He started playing guitar at the age of 9; his 16-year-old brother had died and his parents bought him a guitar, thinking it would help with his grief. He took classical lessons for less than a year in which his teacher taught him "Mary had a Little Lamb", which he did not like very much, and almost stopped completely, until his parents saw an electric guitar at a yard sale and bought it for him. The young Schuldiner immediately took to the instrument. After getting amps, he never stopped playing, writing and teaching himself. Schuldiner was known to spend the weekend in the garage or his room playing his guitar, but was limited to three hours on weekdays when school was in session. Schuldiner first played in public in his early teens.  Schuldiner was originally inspired by Metallica, Iron Maiden, Kiss and classical jazz, among others. He was particularly interested in the metal movement known as NWOBHM - New Wave of British Heavy Metal - and cited bands of that genre among his favorites. He frequently cited French band Sortilege as his personal favorite metal group. Slayer, Celtic Frost, Possessed, Mercyful Fate/King Diamond and Metallica were later influences he would apply more to his own band. Later in his career, Schuldiner frequently cited progressive metal bands such as Watchtower, Coroner and Queensryche as influences. The official Schuldiner website, Empty Words, quotes Schuldiner's mother making the claim that he enjoyed all forms of music except country and rap. He also enjoyed jazz and classical music in addition to metal and British alternative acts such as Lush.  Schuldiner performed well in school before becoming bored with education, and eventually dropped out. He later regretted this decision. He has stated that if he had not become a musician, he would have liked to have become a veterinarian or a cook.
