Few individuals better represent the vicissitudes of invention than Lee de Forest, an ambitious experimenter and inventor
with more than 300 patents, but whose business ventures often failed or became embroiled in litigation. Born in Council Bluffs,
Iowa, on August 26, 1873, de Forest grew up at Talladega College, where his father, Henry Swift De Forest, served as president.
After attending boarding school at Mount Hermon School for Boys, de Forest enrolled at Yale's Sheffield Scientific School
through the DeForest family scholarship, where he earned money from mechanical and gaming inventions, receiving his B.A. in
1896 and Ph.D. in Physics in 1899. Early in his career, de Forest adopted the use of a lower case "d" in "de Forest;" the
rest of his family used an upper case "D."
