]قصة مخترع الصور الفوتوغرافية

سوف أورد قصة مخترع وسوف نستقي منها كثيرا من الدروس على جميع المستويات. النظام الحازم والشفاف قد يكون غير مقبول عند كثير من الناس ولكنه قد يكون السبيل الوحيد للنجاح وحب الوطن.
قصة مُختَرع الصور الفوتوغرافية (تشستر كارلسون) الذي ولد عام 1906، في سياتل في ولاية واشنطن في الولايات المتحدة الأمريكية. كان والداه مريضين بالسل إضافة إلى أن والده كان يعاني من مرض خطير في الظهر مما اضطر كارلسون إلى تحمل مسؤولية منزله في سن مبكرة. ففي الصباح الباكر يقوم بتنظيف المنزل وبعد ذلك يذهب إلى مدرسته. كان طالبا نشيطا فقد أنشأ مجلة كيميائية للمدرسة. تنقل بين عدد من الولايات لتوفير الجو المناسب لوالديه ولكنهما توفيا وهو في سن مبكرة. توفيت والدته عندما كان عمره 17 سنة وبعد ذلك توفي والده.
بعد ما أصبح وحيداً, التحق كارلسون بمعهد كاليفورنيا التقني وحصل على درجة الباكالوريس في علوم الفيزياء، ولكنه كان مدينا للمعهد بمبلغ 140 ألف دولار، ولكي يسدد هذا المبلغ الباهظ، حاول العمل في أكثر من 80 شركة ولكنه لم يقبل.
في عام 1930 م حصل على وظيفة مهندس باحث في معمل بل للتلفونات ولكنه لم يستمر طويلاً في عمله حيث بدأ بدراسة القانون في عام 1936 م وتخرج بعد ثلاث سنوات وشغل منصبا في قسم الاختراعات في إحدى الشركات وكان يحتاج في عمله إلى عمل نسخ عديدة من الرسومات ومواصفات الاختراعات. ولكن لا توجد طريقة تمكنه من الحصول على مبتغاه إلا عن طريق النسخ يدوياً والذي كان يستهلك وقته وجهده. لذا قرر كارلسون الحصول على طريقة تجنبه العناء والتعب الذي يبذله للحصول على نسخ. قرأ كتابا عن الكهرباء الساكنة وبدأ بعمل تجارب في مطبخه الخاص واختبر عددا من المواد من بينها مادة الكبريت. انزعج منه الجيران وأطلقوا عليه اسم (العالم المجنون) وحصل بينه شجار شديد مع امرأة تدعى دوريس أصبحت زوجته فيما بعد.
في عام 1938 م تمكن كارلسون وبمساعدة عالم فيزيائي ألماني يدع اوتوكوريني من عمل أول صورة إلكترو- فوتوغرافية على ورقة شمع.
في عام 1948 م ظهر أول إعلان رسمي عن آلة تصوير من قبل شركة (زيروكس) وبيعت تجارياً أول آلة تصوير في عام 1950 م. وقد حصل كارلسون بعدها على مبلغ قدره 150 مليون دولار عن اختراعه وتبرع بمبلغ 100 مليون دولار للجمعيات الخيرية قبل وفاته عام 1968 م .
أدرج اسم كارلسون في قائمة مشاهير المخترعين الوطنيين، وقد استغرق اختراعه 15 عاماً من البحث لكي يتمكن من اختراع آلة تصوير. قضى معظم وقته في العمل وحيداً أو متنقلا من مكان إلى آخر وقد منح ميداليات وجوائز رفيعة المستوى.
لعل هذه القصة تكون حافزاً لشباب الأمة الإسلامية على الصبر وتحمل المصاعب في سبيل بلوغ الهدف. كذلك تعطينا مثالاً يحتذى به في عملية الإنفاق على مشاريع وأعمال الخير. كم أتمنى من رجال الأعمال أو من لديه إمكانيات المساعدة في إنشاء معامل بحثية في جامعاتنا ومراكز الأبحاث الوطنية .

Chester Carlson

From Wikipedia, the free encyclopedia

, Chester Floyd Carlson (February 8, 1906 – September 19, 1968) was an American physicist, inventor, and patent attorney born in Seattle, Washington.
He is best known for having invented the process of electrophotography, which produced a dry copy rather than a wet copy, as was produced by the mimeograph process. Carlson's process was subsequently renamed xerography, a term that literally means "dry writing."

Early life
Work outside of school hours was a necessity at an early age, and with such time as I had I turned toward interests of my own devising, making things, experimenting, and planning for the future. I had read of Thomas Alva Edison and other successful inventors, and the idea of making an invention appealed to me as one of the few available means to accomplish a change in one's economic status, while at the same time bringing to focus my interest in technical things and making it possible to make a contribution to society as well.

—Chester Carlson, to A. Dinsdale

Carlson's father, Olaf Adolph Carlson, had little formal education, but was described as "brilliant" by a relative. Carlson wrote of his mother, Ellen, that she "was looked up to by her sisters as one of the wisest.
When Carlson was an infant, his father contracted tuberculosis, and also later suffered from arthritis of the spine (a common, age-related disease). When Olaf moved the family to Mexico for a seven-month period in 1910, in hopes of gaining riches through what Carlson described as "a crazy American land colonization scheme," Ellen contracted malaria.

Because of his parents' illnesses, and the resulting poverty, Carlson worked to support his family from an early age; he began working odd jobs for money when he was eight. By the time he was thirteen, he would work for two or three hours before going to school, then go back to work after classes. By the time Carlson was in high school, he was his family's principal provider.[4] His mother died of tuberculosis when he was 17, and his father died when Carlson was 27.
Carlson began thinking about reproducing print early in his life. At age ten, he created a newspaper called This and That, created by hand and circulated among his friends with a routing list. His favorite plaything was a rubber stamp printing set, and his most coveted possession was a toy typewriter an aunt gave him for Christmas in 1916—although he was disappointed that it was not an office typewriter.[5]

While working for a local printer while in high school, Carlson attempted to typeset and publish a magazine for science-minded students like himself. He quickly became frustrated with traditional duplicating techniques. As he told Dartmouth College professor Joseph J. Ermene in a 1965 interview, "That set me to thinking about easier ways to do that, and I got to thinking about duplicating methods."[

Fascinating facts about Chester Carlson
inventor of Xerography in 1938.
Chester F. Carlson

AT A GLANCE:
Although Chester Carlson invented Xerography in 1938, it was twenty-one years later that the first office copier was available to the public. During the first eight months of production, Haloid (later renamed Xerox) sold more copiers then they expected to sell in the products entire life cycle.

The astounding success of xerography is all the more remarkable because it was given little hope of surviving its infancy. For years, it seemed to be an invention nobody wanted. To know why it eventually prevailed is to understand the mind of Chester Carlson. For xerography, and the man who invented it, were both the products of hardship and travail.Chester Carlson was born in Seattle on February 8, 1906, the only child of an itinerant barber. The family settled in San Bernardino, Calif., and at the age of fourteen, Carlson was working after school and on weekends as the chief support of his family. His father was crippled with arthritis and his mother died of tuberculosis when he was seventeen.
Even as a boy, Carlson had the curious mind that always asked the how and why of things. He was fascinated with the graphic arts and with chemistry -- two disciplines he would eventually explore with remarkable result.
As a teenager he got a job working for a local printer, from whom he acquired, in return for his labor, a small printing press about to be discarded. He used the press to publish a little magazine for amateur chemists.
Upon graduating from high school, Carlson worked his way through a nearby junior college where he majored in chemistry. He then entered California Institute of Technology, and was graduated in two years with a degree in physics. More problems faced Carlson as he entered a job market shattered by the developing Depression. He applied to eighty-two firms, and received only two replies before landing a $35-a-week job as a research engineer at Bell Telephone Laboratories in New York City.
As the Depression deepened, he was laid off at Bell, worked briefly for a patent attorney, and then secured a position with the electronics firm of PR. Mallory & Co. While there, he studied law at night, earning a law degree from New York Law School. Carlson was eventually promoted to manager of Mallory's patent department.
"I had my job," he recalled, "but I didn't think I was getting ahead very fast. I was just living from hand to mouth, and I had just gotten married. It was kind of a struggle, so I thought the possibility of making an invention might kill two birds with one stone: It would be a chance to do the world some good and also a chance to do myself some good." As he worked at his job, Carlson noted that there never seemed to be enough carbon copies of patent specifications, and there seemed to be no quick or practical way of getting more. The choices were limited to sending for expensive photo copies, or having the documents retyped and then reread for errors. A thought occurred to him: Offices might benefit from a device that would accept a document and make copies of it in seconds. For many months Carlson spent his evenings at the New York Public Library reading all he could about imaging processes. He decided immediately not to research in the area of conventional photography, where light is an agent for chemical change, because that phenomenon was already being exhaustively explored in research labs of large corporations.
Obeying the inventor’s instinct to travel the uncharted course, Carlson turned to the little-known field of photoconductivity, specifically the findings of Hungarian physicist Paul Selenyi, who was experimenting with electrostatic images. He learned that when light strikes a photoconductive material, the electrical conductivity of that material is increased.
Soon, though, he began some rudimentary experiments, beginning first -- to his wife's aggravation -- in the kitchen of his apartment in Jackson Heights, Queens. It was here that Carlson unearthed the fundamental principles of what he called electrophotography --later to be named xerography -- and defined them in a patent application filed in September, 1938. "I knew," he said, "that I had a very big idea by the tail, but could I tame it?"
So he set out to reduce his theory to practice. Frustrated by a lack of time, and suffering from painful attacks of arthritis, Carlson decided to dip into his meager resources to pursue his research. He set up a small lab in nearby Astoria and hired an unemployed young physicist, a German refugee named Otto Kornei, to help with the lab work.
It was here, in a rented second-floor room above a bar, where xerography was invented. This is Carlson's account of that moment: "I went to the lab that day and Otto had a freshly-prepared sulfur coating on a zinc plate. We tried to see what we could do toward making a visible image.
Otto took a glass microscope slide and printed on it in India ink the notation '10-22-38 ASTORIA.'" We pulled down the shade to make the room as dark as possible, then he rubbed the sulfur surface vigorously with a handkerchief to apply an electrostatic charge, laid the slide on the surface and placed the combination under a bright incandescent lamp for a few seconds. The slide was then removed and lycopodium powder was sprinkled on the sulfur surface. By gently blowing on the surface, all the loose powder was removed and there was left on the surface a near-perfect duplicate in powder of the notation which had been printed on the glass slide.
"Both of us repeated the experiment several times to convince ourselves that it was true, then we made some permanent copies by transferring the powder images to wax paper and heating the sheets to melt the wax. Then we went out to lunch and to celebrate."
Fearful that others might be blazing the same trail as he -- which is not an uncommon occurrence in the history of scientific discovery -- Carlson carefully patented his ideas as he learned more about this new technology. His fear was unfounded. Carlson was quite alone in his work, and in his belief that xerography was of practical value to anyone. He pounded the pavement for years in a fruitless search for a company that would develop his invention into a useful product.
From 1939 to 1944, he was turned down by more than twenty companies. Even the National Inventors Council dismissed his work. "Some were indifferent," he recalled, "several expressed mild interest, and one or two were antagonistic. How difficult it was to convince anyone that my tiny plates and rough image held the key to a tremendous new industry. "The years went by without a serious nibble.. .I became discouraged and several times decided to drop the idea completely. But each time I returned to try again. I was thoroughly convinced that the invention was too promising to be dormant."
Finally, in 1944, Battelle Memorial Institute, a non-profit research organization, became interested, signed a royalty-sharing contract with Carlson, and began to develop the process. And in 1947, Battelle entered into an agreement with a small photo-paper company called Haloid (later to be known as Xerox), giving Haloid the right to develop a xerographic machine.
It was not until 1959, twenty-one years after Carlson invented xerography, that the first convenient office copier using xerography was unveiled. The 914 copier could make copies quickly at the touch of a button on plain paper. It was a phenomenal success. Today, xerography is a foundation stone of a gigantic worldwide copying industry, including Xerox and other corporations which make and market copiers and duplicators producing billions and billions of copies a year. And to Carlson, who had endured and struggled for so long, came fame, wealth and honor, all of which he accepted with a grace and modesty much in keeping with his shy and quiet personality.
Had he held onto it all, Carlson would have earned well over $150 million from his remarkable invention. But before he died he had given away some $100 million to various foundations and charities. During Carlson's last years he was given dozens of honors for his pioneering work, including the Inventor of the Year in 1964 and the Horatio Alger Award in 1966.
