Lee De Forest

Lee De Forest was born Aug. 26, 1873, Council Bluffs, Iowa. De Forest was the son of a Congregational minister. His father moved the family to Alabama and there assumed the presidency of the nearly bankrupt Talladega College for Negroes. Excluded by citizens of the white community who resented his father 's efforts to educate blacks, Lee and his brother and sister made friends from among the black children of the town and spent a happy although sternly disciplined childhood in this rural community. (Kraeuter, 74). As a child he was fascinated with machinery and was often excited when hearing of the many technological advances during the late 19th century. He began tinkering and inventing things even in high school, often trying to build things that he could sell for money. By the age of 13 he was an enthusiastic inventor of mechanical gadgets such as a miniature blast furnace and locomotive, and a working silverplating apparatus. (A Science Odyssey: People and Discoveries).

His father had planned for him to follow him in a career in the clergy, but Lee wanted to go to school for science and, in 1893, enrolled at the Sheffield Scientific School of Yale University, one of the few institutions in the United States then offering a first-class scientific education. (Kraeuter, 74). De Forest went on to earn the Ph.D. in physics in 1899, with the help of scholarships, and money his parents made by working odd jobs. By this time he had become interested in electricity, particularly the study of electromagnetic wave propagation, then being pioneered chiefly by the German Heinrich Rudolf Hertz and the Italian Guglielmo Marconi. De Forest 's doctoral dissertation on the "Reflection of Hertzian Waves from the Ends of Parallel Wires" is said to possibly be the first doctoral thesis in the United States on the subject that was later to become known as radio. (Kraeuter, 76).

His first job was with the Western Electric Company in

    Gatling. This man was in no way considered a novice inventor. He had started very young, which resulted in him becoming independently wealthy by 1861. As a boy, he had attempted to perfect the invention of a cotton seed planter and a machine for thinning young cotton plants. By the time he was twenty, he went into business for himself. His first ever solo invention was a propulsions screw for steam powered ships. Unfortunately an almost identical design had been patented just a few short months earlier. He would later go on to invent a wheat planting drill in 1839, a double-action hemp break in 1850, a steam tractor in 1857, a steam powered ram and a new gunmetal alloy during the war years, and a motorized tractor many years later. Also during the war years, he obviously invented the Gatling Gun. His inspiration for building this gun may seem a little backwards to most people. His large motivation was humanitarian concerns. Gatling had claimed that the Gatling Gun would help to end the war or too costly. Once again, reasoning may make no sense to you. He had felt the gruesome killing machine would deter people from entering war as well as making it less appealing. The Union, however, had decided to investigate, believing that he was a supporter of the Confederacy. This was true since he was part of the Order of American Knights, which was a secret group of Confederate sympathizers and saboteurs. He sympathies, however, during the Civil War were neatly divided. The investigation did not lead to…

At only 13 years old, young Ford decided to surprise his farm-grazing family by taking apart and fixing a pocket watch; unsurprisingly, these rural people were dumbfounded. At 16, Henry Ford couldn’t stand this boring, useless life on the farm. So, he ditched his family and apprenticed a machinist. In 1893, Ford was so smart that Thomas Edison, the person who made the lightbulb a thing, gave him a job at Edison Illuminating Company as a chief engineer. During his times, Ford made the Ford Quadricycle, the first try at a horseless car. Then, with Thomas Edison’s, support, Henry Ford invented the Model T car, the first cheap automobile car.…
