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.

Did he make any other improvements?

Numerous other improvements that made for easier manufacture and installation were continually implemented.

Robert Swan Mueller III (; born August 7, 1944) is an American attorney who served as the sixth Director of the Federal Bureau of Investigation from 2001 to 2013. A Republican, he was appointed by President George W. Bush; President Barack Obama gave his original ten-year term a two-year extension, making him the longest-serving FBI director since J. Edgar Hoover. He is currently head of the Special Counsel investigation of Russian interference in the 2016 United States elections and related matters. A graduate of Princeton University, Mueller served as a Marine Corps officer during the Vietnam War, receiving the Bronze Star Medal with Combat "V" for heroism and the Purple Heart Medal.
Mueller was accepted for officer training in the United States Marine Corps in 1968, attending training at Parris Island, Officer Candidate School, Army Ranger School, and Army jump school. In July 1968, he was sent to South Vietnam, where he served as a rifle platoon leader with Second Platoon, H Company, 2nd Battalion, 4th Marines, 3rd Marine Division. In December 1968, he earned the Bronze Star with 'V' distinction for combat valor for rescuing a wounded Marine under enemy fire during an ambush that saw half of his platoon become casualties. In April 1969, he received an enemy gunshot wound in the thigh, recovered, and returned to lead his platoon until June 1969. For his service in and during the Vietnam War, his military decorations and awards include: the Bronze Star Medal with Combat "V", Purple Heart Medal, two Navy and Marine Corps Commendation Medals with Combat "V", Combat Action Ribbon, National Defense Service Medal, Vietnam Service Medal with three service stars, Republic of Vietnam Gallantry Cross, Republic of Vietnam Campaign Medal, and Parachutist Badge. Mueller eventually became aide-de-camp to 3rd Marine Division's commanding general, then-Major General William K. Jones, where he "significantly contributed to the rapport" Jones had with other officers, according to one report. Reflecting on his service in the Vietnam War, Mueller said, "I consider myself exceptionally lucky to have made it out of Vietnam. There were many--many--who did not. And perhaps because I did survive Vietnam, I have always felt compelled to contribute." After returning from Vietnam, Mueller was briefly stationed at Henderson Hall, before leaving active-duty service in August 1970. He was inducted into the Ranger Hall of Fame in 2004.

What did he do after training?
In July 1968, he was sent to South Vietnam, where he served as a rifle platoon leader
