Inventor of Xerography: Chester F. Carlson
Chester Carlson was honored with the printing of a 21 cent stamp, which was issued first on October 21, 1988. He was knows as the "Father of Xerography" (see image to the right).
Carlson was born into abject poverty and spent all of his boyhood and early manhood in its tight grip. Homelessness was a constant threat throughout his childhood. By age 12, Carlson had to work to help his parents, and by 14 he had become the family's main breadwinner. In a well-written biography of Carlson, David Owen explains that "[Carlson] was a shy, soft-spoken boy who, deep within himself, couldn't help sharing his parents' deepening despair about the precariousness of their existence." And yet, the young Carlson would not let poverty crush his spirit as it had done to his father. He continued to go to school, while working to support his family, and developed a strong interest in science. With little hope of going to college, the adolescent Carlson was convinced that a career as an inventor was the only way he could use his technical talents to break free of poverty. Stories of successful inventors like Edison had made a strong impression on Carlson. In high school, Carlson started to keep a notebook on ideas for inventions. Though devastated by his mother's death and left to take care of an invalid father, Carlson's desire to learn was too strong not to go to college. Carlson got into Cal Tech and managed to graduate in physics with decent grades, although he had to work to support himself and his father. He regretted going to Cal Tech. Poverty made Carlson feel like an outsider. And yet, in later years, Carlson observed that his rigorous grounding in science and math proved very useful to his work in xerography. The inner strength he summoned to educate himself not only gave him the technical skills to invent a bold idea, but it also prepared him to wage a single-handed battle to pursue an invention that others thought was a useless curiosity.
In retrospect, one could say that patent #2,221,776 ushered in a revolution in printing technology and stupendous business opportunities. But at the time, no one saw any significance or value in it. Carlson knocked on numerous big corporate doors, including GE, RCA and IBM. The response was an unequivocal "not interested." Sustained only by a quiet, but deep inner strength, Carlson worked in relative obscurity trying to develop a demonstration that photoconductivity and electrostatics could indeed provide a workable framework for copying documents. The early work in xerography did not emerge from the large, well equipped, and sophisticated R&D laboratory. Instead, Carlson toiled away in crude makeshift labs, sometimes using his kitchen, other times a rented backroom.
In 1944, Carlson's hope to commercialize "electron photography" got a boost when the Batelle Memorial Institute and the Haloid Company got involved. But even then it would take another 15 years before the Haloid Company would produce a successful xerographic machine, the 914. Carlson's patent was the crucial first step. But it took a team of talented scientists and engineers and a good deal of money to solve the large number of very difficult technical problems that blocked xerography's successful commercialization. According to Owen, "Carlson's most important contribution to the project during the 1950s was probably helping to maintain the company's enthusiasm for his idea, despite repeated setbacks."
The 914 was an enormous success, and within a few years it catapulted the insignificant Haloid Company to the Xerox Corporation — the fifteenth largest company in the United States. Carlson had become extremely wealthy. The adolescent's dream had come true: a great invention had indeed freed him from poverty. Although wealthy, Carlson lived simply. He preferred to give away his considerable wealth to a variety of social causes. Hardship had not only given Carlson enormous inner strength, it also had opened up his heart to the needs of society.
