Some context: 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.
How long did he work with McGrigor?
A: 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.
Some context: Tristano was born in Chicago on March 19, 1919. His mother, Rose Tristano (nee Malano), was also born in Chicago. His father, Michael Joseph Tristano, was born in Italy and moved to the United States as a child. Lennie was the second of four brothers.
Tristano's second album for Atlantic was recorded in 1961 and released the following year. The New Tristano, as was stressed on the album cover, consisted entirely of piano solos and no overdubbing or tape-speed manipulation was employed. The tracks contain left-hand bass lines that provide structure to each performance as well as counterpoint for the right-hand playing; block chords, unclear harmonies and contrasting rhythms also appear. Other solo piano recordings that Tristano made in 1961 were not released until the 1970s. Tristano and his wife formally divorced in 1962. Their son, Steve, who was born in 1952, met his father only once after their initial 1956 separation. Tristano married again in the early 1960s. His second wife was Carol Miller, one of his students. They had a son, Bud, and two daughters, Tania and Carol. The couple divorced in 1964, and Tristano later lost a custody battle with his ex-wife over the children. In 1964 the pianist reformed his quintet with Konitz and Marsh for a two-month engagement at the Half Note and more performances in Canada. The quartet, missing Konitz, played in Toronto again in the following year. Tristano played on occasion at the Half Note Club until the mid-1960s, and toured Europe in 1965. His European tour was mainly as a solo pianist, and the playing was in the style of his The New Tristano recordings. He performed with Ind and others in concerts in the UK in 1968; they were well received, and Tristano returned the following year. His last public performance in the US was in 1968. Tristano declined offers to perform in the 1970s; he explained that he did not like to travel, and that the requirement for a career-minded musician to play concerts was not something that he wanted to follow. He continued teaching, and helped to organize concerts for some of his students. Another album, Descent into the Maelstrom, was released in the 1970s; it consisted of recordings made between 1951 and 1966. Tristano had a series of illnesses in the 1970s, including eye pain and emphysema (he smoked for most of his life). On November 18, 1978 he died of a heart attack at home in Jamaica, New York.
What was the first thing he did according to the article

Some context: Donnie Iris (born Dominic Ierace on February 28, 1943) is an American rock musician known for his work with the Jaggerz and Wild Cherry during the 1970s, and for his solo career beginning in the 1980s with his band, the Cruisers. He wrote the #2 Billboard hit, "The Rapper", with the Jaggerz in 1970 and was a member of Wild Cherry after the group had a #1 hit with "Play That Funky Music." He also achieved fame as a solo artist in the early 1980s with the #29 hit "Ah! Leah!"
Dominic Ierace was born in New Castle, Pennsylvania, but grew up in Ellwood City, Pennsylvania. The son of father Sam and mother Carrie Ierace, young Dominic began to learn how to sing at an early age from his mother, who had sung in Curly Venezie's orchestra. He practiced earlier on by singing along with his mother's favorite singers, Frank Sinatra and Tony Bennett. Per his mother's encouragement, Ierace began singing at weddings at age five, and by eight was performing on local television and entering talent contests. Over time, Ierace began to develop his own interests in music with the advent of rock music, drawing inspiration from Elvis Presley and Buddy Holly and later from the Beatles, the Rolling Stones and even R&B and soul artists Marvin Gaye and Ray Charles in addition to other Motown acts. The popularity of rock and roll inspired Ierace to become a self-taught guitarist. When his voice changed around age 12, he gave up singing and took up the drums. About the time he was a senior in high school (circa 1961), Ierace's voice changed again, and he got back into singing. He formed a vocal doo-wop group called the Fabutons with Johnny Roth, Anthony Matteo, Lou Delessandro and Chuckie Hasson and performed gigs around Beaver and Lawrence counties in Pennsylvania. However, the group only performed a few times before they disbanded and Ierace went to college. While attending Slippery Rock State College, Ierace formed a band called the Tri-Vels with guitarist Jim Evans and drummer Dave Amodie, two fellow students at Slippery Rock. With the addition of bassist Dave Reiser, they renamed themselves Donnie and the Donnells. This band in both incarnations played R&B and pop rock covers at fraternity parties and lasted from about 1961 to 1964.
After disbanding, did Iris find a new band?
