input: 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.

input: Baum was born in Chittenango, New York in 1856 into a devout Methodist family. He had German, Scots-Irish, and English ancestry, and was the seventh of nine children of Cynthia Ann (nee Stanton) and Benjamin Ward Baum, only five of whom survived into adulthood. "Lyman" was the name of his father's brother, but he always disliked it and preferred his middle name "Frank".  His father succeeded in many businesses, including barrel-making, oil drilling in Pennsylvania, and real estate. Baum grew up on his parents' expansive estate called Rose Lawn, which he fondly recalled as a sort of paradise. Rose Lawn was located in Mattydale, New York. Frank was a sickly, dreamy child, tutored at home with his siblings. From the age of 12, he spent two miserable years at Peekskill Military Academy but, after being severely disciplined for daydreaming, he had a possibly psychogenic heart attack and was allowed to return home.  Baum started writing early in life, possibly prompted by his father buying him a cheap printing press. He had always been close to his younger brother Henry (Harry) Clay Baum, who helped in the production of The Rose Lawn Home Journal. The brothers published several issues of the journal, including advertisements from local businesses, which they would give to family and friends for free. By the age of 17, Baum established a second amateur journal called The Stamp Collector, printed an 11-page pamphlet called Baum's Complete Stamp Dealers' Directory, and started a stamp dealership with friends.  At 20, Baum took on the national craze of breeding fancy poultry. He specialized in raising the Hamburg. In March 1880, he established a monthly trade journal, The Poultry Record, and in 1886, when Baum was 30 years old, his first book was published: The Book of the Hamburgs: A Brief Treatise upon the Mating, Rearing, and Management of the Different Varieties of Hamburgs.  Baum had a flair for being the spotlight of fun in the household, including during times of financial difficulties. His selling of fireworks made the Fourth of July memorable. His skyrockets, Roman candles, and fireworks filled the sky, while many people around the neighborhood would gather in front of the house to watch the displays. Christmas was even more festive. Baum dressed as Santa Claus for the family. His father would place the Christmas tree behind a curtain in the front parlor so that Baum could talk to everyone while he decorated the tree without people managing to see him. He maintained this tradition all his life.

input: After being discharged from the Army in 1946, Serling worked at a rehabilitation hospital while recovering from his wounds. His knee troubled him for years. Later, his wife became accustomed to the sound of him falling down the stairs when his knee buckled under his weight.  When he was fit enough, he used the federal G.I. bill's educational benefits and disability payments to enroll in the physical education program at Antioch College in Yellow Springs, Ohio. He had been accepted to Antioch (his brother's alma mater) while in high school. His interests led him to the theater department and then to broadcasting. He changed his major to Literature and earned his Bachelor of Arts degree in 1950. "I was kind of mixed up and restless, and I kind of liked their work-for-a-term, go-to-school-for-a-term set-up," he recounted.  As part of his studies, Serling became active in the campus radio station, an experience which proved useful in his future career. He wrote, directed, and acted in many radio programs on campus, then around the state, as part of his work study. Here he met Carolyn Louise "Carol" Kramer, a student, who later became his wife. At first, she refused to date him because of his campus reputation as a "ladies man", but she eventually changed her mind. He converted from Judaism to Unitarianism in college, which allowed him to marry Kramer on July 31, 1948. They had two daughters, Jodi and Anne.  Carol Serling's maternal grandmother, Louise Taft Orton Caldwell, had a summer home on Cayuga Lake in Interlaken, New York, which was the newlyweds' honeymoon destination. The Serling family continued to use this house annually throughout Rod's life, missing only two summers in the years when his daughters were born.  For extra money in his college years, Serling worked part-time testing parachutes for the United States Army Air Forces. According to his radio station coworkers, he received $50 for each successful jump and had once been paid $500 (half before and half if he survived) for a hazardous test. His last test jump was a few weeks before his wedding. In one instance, he earned $1,000 for testing a jet ejection seat that had killed the previous three testers.
