Biography of Chester Carlson, Inventor of the Photocopier

Biography of Chester Carlson, Inventor of the Photocopier – Chester Carlson is a physicist, inventor and patent advocate from the United States. His name is known as the inventor of the photocopier in 1938. Chester Carlson’s invention is still used by millions of people in the world today.

In fact, the problem that triggered Chester Carlson to invent the photocopier came from his difficulties in studying and working. He succeeded in inventing the photocopier because of his studies and work which required him to make copies of large amounts of data in a short time.

Youth and education

Chester Carlson was born on February 8, 1906 in Seattle, Washington DC, United States. At the age of four, he moved to Mexico for seven months, after his father suffered from tuberculosis and arthritis.

Chester’s parents hope that Mexico will change their family’s fate for the better. However, not long afterward, his mother suffered from malaria, causing them to fall into poverty.

Since 1914, or when he was eight years old, Chester had to earn money to help his family financially. This condition encouraged him to think creatively and was able to create a newspaper called “This and That” at the age of 10.

The handwr At this age, Chester had two favorite objects, namely a stamp printing set and a toy typewriter that his aunt gave him.

When he was in high school, he became the backbone of the family, especially after his mother died. At that time, Chester, who worked as a document copyist, felt frustrated with traditional duplication techniques.

Since then, he began to seriously think about easier and more modern ways or methods of duplication. Because he had to study and work, he studied at Riverside Junior College majoring in chemistry and then switching to physics.

After three years at Riverside Junior College, Chester then moved to the California Institute of Technology where he graduated in 1930. However, even though his grades were quite good, he was not accepted into the 82 companies he applied to. itten newspaper was circulated to his friends.

Discover photocopying techniques

In the end, Chester Carlson was accepted to work at Nokia’s company in New York. He briefly worked in the research division, before finally being moved to become an assistant patent attorney for the company.

At that time, Chester again had difficulty making copies of patent documents. He became increasingly serious about trying to find a duplication method that was easier, more modern and efficient than the method that existed at that time.

However, in 1933, the economic crisis forced Chester to be fired from his job. Not long afterward, he got a better job at electronics company PR Mallory Company, as head of the patent department.

Between 1936-1939, Chester studied law at New York Law School. Because he couldn’t afford to buy books, he was forced to copy material by taking notes in the library. The pain caused by the tedious copying made him determined to find a way to invent a photocopier.

Since then, he began to actively carry out experiments at his residence, until several fire incidents occurred. Chester continued to pursue the idea of ​​making a photocopier by developing an electrostatic attraction process that caused powder to stick to paper.

This method was successful during trials in October 1938, which was then called the xerography or electrophotography technique. Chester’s photocopying method is capable of producing clean, dry and fast copies of documents.

Developing a photocopier

Knowing that his discovery was very important for the world, Chester Carlson succeeded in obtaining a patent in 1940. Seven years later, he collaborated with the Haloid Company to develop his invented photocopier.

Haloid Company then changed its name to Xerox Corporation, which is currently known as a company providing photocopying equipment, digital printers and several other office equipment. In 1959, Xerox Corporation introduced the first automatic photocopier, named the Xerox 914.

The machine was capable of copying up to 100,000 papers per month and was very popular in its time. For Chester, the commercial success of the Xerox 914 was the culmination of his mission, namely to create a device capable of making exact copies of existing documents quickly and cheaply.

Died

After the Xerox 914 went into production, Chester Carlson’s involvement with Xerox declined, as he began pursuing his philanthropic interests. Chester Carlson died on September 19, 1968 of a heart attack while watching the film He Who Rides a Tiger.

To honor his invention, in 1981, his name was inducted into the National Inventors Hall of Fame.
