IN: 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.

IN: Pete Maravich was born to Petar "Press" Maravich (1915-1987) and Helen Gravor Maravich (1925-1974) in Aliquippa, a steel town in Beaver County in western Pennsylvania, near Pittsburgh. Maravich amazed his family and friends with his basketball abilities from an early age. He enjoyed a close but demanding father-son relationship that motivated him toward achievement and fame in the sport. Maravich's father was the son of Serbian immigrants and a former professional player-turned-coach.

Maravich was survived by his wife Jackie and his two sons Jaeson, who was 8 years old, and Josh, aged 5. Only the previous year, Maravich had taken Jaeson to the 1987 NBA All-Star Game in Seattle, Washington, and introduced him to Michael Jordan.  Since Maravich's children were very young when he died, Jackie Maravich initially shielded them from unwanted media attention, not even allowing Jaeson and Josh to attend their father's funeral. However, a proclivity to basketball seemed to be an inherited trait. During a 2003 interview, Jaeson told USA Today that, when he was still only a toddler, "My dad passed me a (Nerf) basketball, and I've been hooked ever since... . My dad said I shot and missed, and I got mad and I kept shooting. He said his dad told him he did the same thing."  Despite some setbacks coping with their father's death and without the benefit that his tutelage might have provided, both sons eventually were inspired to play high school and collegiate basketball--Josh at his father's alma mater, LSU.  On June 27, 2014, Governor Bobby Jindal proposed that LSU erect a statue of Maravich outside the Assembly Center which already bears the basketball star's name. Former coach Dale Brown opposes such a monument, but Maravich's widow, Jackie McLachlan, said that she had been promised a statue after the passing of her husband. McLachlan said that she has noticed how fans struggle to get the Maravich name on the Assembly Center into a camera frame.  In February 2016, the LSU Athletic Hall of Fame Committee unanimously approved a proposal that a statue honoring Maravich be installed on the campus.
