On October 22, 1938, Chester F. Carlson, an American physicist, inventor, and patent attorney, successfully demonstrated the first xerographic image at the Astoria Hotel in Queens, New York. This groundbreaking invention would later become known as the xerox machine, revolutionizing the way we copy and print documents.
Carlson had been working on the idea of xerography, a dry copying process using electrostatic charges, for several years. He faced numerous challenges and setbacks, as many people believed his idea was impossible. Undeterred, Carlson persisted in his research and experimentation.
On that fateful day in 1938, Carlson and his assistant, Otto Kornei, created the first xerographic image. They wrote the words "10-22-38 ASTORIA" on a microscope slide, coated it with a thin layer of sulfur, and electrostatically charged the surface. They then projected light onto the slide, causing the charges to dissipate in the areas exposed to light. Finally, they dusted the slide with lycopodium powder, which adhered to the remaining charged areas, creating a visible image.
This first xerographic print marked a significant milestone in the history of printing and copying. However, it would take another two decades for Carlson's invention to be developed into a commercial product. In 1959, the Xerox Corporation introduced the Xerox 914, the first automatic plain-paper copier, which became an instant success and changed office work forever.
Carlson's persistence and dedication to his vision ultimately paid off, as his invention has had a lasting impact on society. The ability to make quick, easy, and inexpensive copies has transformed the way information is disseminated and preserved across various fields, including business, education, and government. Today, we celebrate Chester F. Carlson's ingenuity and the birth of xerography, which occurred on this day in 1938.
