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.

In 1776, the first engines were installed and working in commercial enterprises. These first engines were used to power pumps and produced only reciprocating motion to move the pump rods at the bottom of the shaft. The design was commercially successful, and for the next five years Watt was very busy installing more engines, mostly in Cornwall for pumping water out of mines.  These early engines were not manufactured by Boulton and Watt, but were made by others according to drawings made by Watt, who served in the role of consulting engineer. The erection of the engine and its shakedown was supervised by Watt, at first, and then by men in the firm's employ. These were large machines. The first, for example, had a cylinder with a diameter of some 50 inches and an overall height of about 24 feet, and required the construction of a dedicated building to house it. Boulton and Watt charged an annual payment, equal to one third of the value of the coal saved in comparison to a Newcomen engine performing the same work.  The field of application for the invention was greatly widened when Boulton urged Watt to convert the reciprocating motion of the piston to produce rotational power for grinding, weaving and milling. Although a crank seemed the obvious solution to the conversion Watt and Boulton were stymied by a patent for this, whose holder, James Pickard, and associates proposed to cross-license the external condenser. Watt adamantly opposed this and they circumvented the patent by their sun and planet gear in 1781.  Over the next six years, he made a number of other improvements and modifications to the steam engine. A double acting engine, in which the steam acted alternately on the two sides of the piston was one. He described methods for working the steam "expansively" (i.e., using steam at pressures well above atmospheric). A compound engine, which connected two or more engines was described. Two more patents were granted for these in 1781 and 1782. Numerous other improvements that made for easier manufacture and installation were continually implemented. One of these included the use of the steam indicator which produced an informative plot of the pressure in the cylinder against its volume, which he kept as a trade secret. Another important invention, one which Watt was most proud of, was the parallel motion which was essential in double-acting engines as it produced the straight line motion required for the cylinder rod and pump, from the connected rocking beam, whose end moves in a circular arc. This was patented in 1784. A throttle valve to control the power of the engine, and a centrifugal governor, patented in 1788, to keep it from "running away" were very important. These improvements taken together produced an engine which was up to five times as efficient in its use of fuel as the Newcomen engine.  Because of the danger of exploding boilers, which were in a very primitive stage of development, and the ongoing issues with leaks, Watt restricted his use of high pressure steam - all of his engines used steam at near atmospheric pressure.

IN: Simon was born in Washington, D.C., the son of Dorothy Simon (nee Ligeti), a homemaker, and Bernard Simon, a former journalist and then public relations director for B'nai B'rith for 20 years. In March 1977, when Simon was still in high school, Simon's father was one of a group of over 140 people held hostage (and later released) in Washington, D.C. by former national secretary of the Nation of Islam Hamaas Abdul Khaalis in the Hanafi Siege. Simon was raised in a Jewish family with roots that originated in Eastern Europe and Hungary (his maternal grandfather had changed his surname from "Leibowitz" to "Ligeti"). He has a brother, Gary Simon, and a sister, Linda Evans, who died in 1990.

The publishers of Homicide: A Year on the Killing Streets were eager for a screen adaptation and submitted it to numerous directors but there was little interest. Simon suggested that they send the book to Baltimore native and film director Barry Levinson. Levinson's assistant Gail Mutrux enjoyed the book and both she and Levinson became attached as producers. The project became the award-winning TV series Homicide: Life on the Street (1993-1999), on which Simon worked as a writer and producer.  Simon was asked by Mutrux to write the show's pilot episode but declined, feeling he did not have the necessary expertise. He collaborated with his old college friend David Mills to write the season two premiere "Bop Gun". The episode was based on a story by executive producer Tom Fontana and featured Robin Williams in a guest starring role that garnered the actor an Emmy nomination. Simon and Mills won the WGA Award for Best Writing in a Drama for the episode. Simon also received Austin Film Festival's Outstanding Television Writer Award in 2010.  Simon left his job with the Baltimore Sun in 1995 to work full-time on Homicide: Life on the Street during the production of the show's fourth season. Simon wrote the teleplay for the season four episodes "Justice: Part 2" and "Scene of the Crime" (with Anya Epstein). For season five he was the show's story editor and continued to contribute teleplays writing the episodes "Bad Medicine" and "Wu's on First?" (again with Epstein). He was credited as a producer on the show's sixth and seventh seasons. He wrote the teleplays for parts two and three of the sixth season premiere "Blood Ties" (the latter marking his third collaboration with Epstein) and provided the story for the later sixth season episodes "Full Court Press" and "Finnegan's Wake" (with James Yoshimura). He provided the story for the seventh season episodes "Shades of Gray" (with Julie Martin), "The Same Coin" (again with Yoshimura) and "Self Defense" (with Eric Overmyer). Simon wrote the story and teleplay for the seventh season episodes "The Twenty Percent Solution" and "Sideshow: Part 2". Simon, Martin and teleplay writer T. J. English won the Humanitas Prize in the 60 minutes category for the episode "Shades of Gray". Simon was nominated for a second WGA Award for Best Writing in a Drama for his work on "Finnegan's Wake" with Yoshimura and Mills (who wrote the teleplay).  Simon has said that he thought the show was a "remarkable drama" but that it did not reflect the book. He has also said that when writing for the show he had to put his experiences of the real detectives aside as the characters became quite different, particularly in their more philosophical approach to the job. Simon said that TV must find shorthand ways of referencing anything real.
