Biography
John Atanasoff
John Vincent Atanasoff is an American physicist, mathematician and electric engineer of Bulgarian origin, the creator of the first electronic, non-programmable computer. John Atanassov was born on October 4, 1903, a few miles west of Hamilton, New York. His father - Ivan Atanasov was born in the village of Boyadzhik, Yambol. His parents died in the April Uprising. In 1889, the 13-year-old Ivan Atanasov emigrated to the United States with his uncle. John Atanasoff's mother is Iva Lucena Purdy, a math teacher. John Jr. is the first of 9 children of Iva and Ivan. Soon after his birth, Ivan Atanasov became a senior engineer in Austin, and then in Brewster, Florida, where John Atanassov Jr. graduated from school. In 1921, John went to the University of Gainesville, Florida to study electrical engineering because his most sought-after specialty was not covered in the Gainesville University curriculum. Meanwhile, he began to get interested in electronics and continued with mathematics. Atanasov received his Bachelor's degree in Electrical Engineering in 1925 with honors, and then began teaching at the Iowa State College. In fact, this was not the only offer he received - he was invited by many universities, including Harvard, but he chose Iowa College because he got the first offer from the Iowa College of Engineers and Science. After joining Iowa, from September to November, John worked on his master's degree. Then he met Lura Mike, his future wife. In June 1926, John Atanassov received his Masters Degree in Mathematics in Iowa, where he was employed as a lecturer. Married to Lura Mike, about a year later, the first of their three children, Elsie, was born. The others are Joan and John Atanassov III. When their daughter turned 1 year old, the young family moved to Madison, Wisconsin, where John got admitted as a doctoral student. His thesis "Dielectric Helium Constant" was related to a large number of complex calculations. The tiring hours of the Monro Mechanical Calculator (which was one of the best for his time) made the young scientist think about the idea of a more sophisticated computing machine. After receiving his Ph.D. in Physics in July 1930, John returned to Iowa, determined to try to create a better and faster computer. In 1926 he became a Master of Mathematics at the Iowa State College, he was an associate professor of mathematics and physics. At the University of Winchester he got the title of "Doctor of Physics". John Atanasoff received many awards, scientific degrees and his name become known to the public. Getting Started on the Complex Math Trail John is the first of the 10 children in the family. Only 9 years old, he repaired faulty wires in the porch lamps. He was interested in baseball while his father showed him the logarithmic line he bought for his engineering work. He completely conquered it. John took a close look at the intrusions and was amazed at the fact, how he helped with the correct answers. Months later, the gifted 9-year-old boy was foremost in his pursuits. During that time he learned from his mother about the number systems with basics other than 10, which encouraged him to study the binary.
THE CONTRIBUTION OF JOHN ATANASOV
John Atanassov has given the world an electron digital numeric calculus and electronic information processing. He is the first, who performed automatic calculus with numbers represented by electronic mediums, not through the ones used before mechanical mediums. His remarkable contribution is also to the introduction of binary numeral systems. "And before Atanassov we had computers, but without Atanassov there would be no information era, there would be no Internet and mobile phones would not have been precise military weapons ". Academician B. Sendov
Creating Your Computer ABC
After experiments with the various devices available at that time Atanasov first introduced the concept of "analog computer". In 1936, together with Glenn Murphy, a colleague of the atomic physicist, created a small analogue calculus for surface geometry research, called Laplaceometer. Atanassov found that he had the same drawbacks as all other analog devices - his accuracy depends on the operation of other parts of the machine. In the winter of 1937-38 his strong desire to solve the problem resulted. One night, frustrated by the many efforts, he got on his car and drove without a specific direction. After two hundred kilometers, he stopped at a roadside facility in Illinois. There, in a glass of bourbon, he soon discovered that his thoughts were stacked and the idea of a brand new type of machine, which differed from what was known until then, was born. It had to be built on the basis of electronic elements, to consider binary numbers instead of decimals used so far and to have a separate regenerative (with capacitors) memory from the processor. Besides physicist and mathematician, Atanasov was also a highly qualified expert in electronic engineering, which helped him design the concrete circuit solutions. In March 1939, his university awarded $ 650, and Atanassov and Berry began work, and the assembly of the machine took place at the ground floor of the Physics Laboratory. For a few months, they both created and perfected a prototype computing machine, later called Atanasoff-Berry's computer or ABC (Atanasoff-Berry Computer). Atanasov planned to save in memory and automatically submit a series of commands in the calculation process, ie. to use software. In December 1940, Atanassov met John Mockley for the first time during a conference, and because of his keen interest in the machine and its principle of work, he invited Mockley to visit Ames. Molly visits Atanassov and visits his home for five days during which they discuss the construction of the computer ABC, as well as other Atanasov's ideas related to computing. Mokley also read the manuscript of an article describing the machine. During the visit the computer was almost finished and the guest was acquainted in detail with his principle of work and technical realization. Discussions with Atanasoff and his assistant were friendly and frank. Subsequently, in the 1973 trial, the court came to the conclusion that as a result of this visit, the discussions with Atanassov and Berry, the demonstrations and the acquaintance with the manuscript, Mokli derived from ABC "the invention of an automatic digital computer" .
The patent dispute
The patent dispute, i. the litigation about the discovery of the computer marked a major part of John Atanassov's life. It has been running for years - from 1966 to 1973, hundreds of pages have been printed with testimony on the technical side of the dispute, many experts were questioned, and Atanasov was the chief witness. Finally, on October 19, 1973, the Federal Court issued a decision that ruins the myth that the first electronic computing machine was created by John W. McClint and John P. Eckert. The judgment declares the ENIAC patent invalid, and finds that Moklyn and Eckert have borrowed the fundamental principles of the invention from John Atanassov.
Atanasov and Bulgaria
John Atanasov visited Bulgaria twice. His first visit was in 1970 at the initiative of Academician Blagovest Sendov. Here he was awarded the Cyril and Methodius Order - first degree. John Atanassov then gave several lectures at the Bulgarian Academy of Sciences dedicated to the invention of the computer. His second visit was in May - June 1985. John Atanasov was already recognized as the inventor of the unprogrammable computer because the historic litigation has ended in his favor. Then he was awarded the Order of the People's Republic of Bulgaria - first degree. He also visited the birthplace of his father - Boyadzhik, Yambol village. He is Honorary Citizen of Yambol.
Along with his two Bulgarian orders, Atanasov has already received the greatest scientific recognition of Bulgaria - in 1983 he was elected a foreign member of the Bulgarian Academy of Sciences, and since 1988 the name of Atanasoff is also circulating in the cosmos - the so-called first asteroid, discovered and studied by Bulgarians at the Rozhen National Astronomical Observatory.
FOREST FOR BULGARIA
Apart from many other things, Bulgarians today also need well-founded national self-confidence. The sources for such self-esteem are our history and the talents of people with Bulgarian blood. For the past century, one of the highest peaks in this respect is John Atanassov, the inventor of the world's first electronic computer. The meaning of each action is determined by its consequences. John Atanassov's invention is the beginning of an information revolution that transforms and continues to transform the world. What exactly did John Atanassov do? The idea of a computer-controlled computer has been known more than 100 years before John Atanassov began designing his computer. This idea belongs to the English mathematician Charles Babbage, but was not made by him due to technical difficulties associated with the implementation of the computer by metal components. A great variety of calculating machines were built before John Atanassov, but again purely mechanical. John Atanassov's great and decisive breakthrough is the abandonment of mechanics and the creation of electronic calculus schemes using the representation of numbers in a binary system. Now it is very simple to see, but the genius is in overcoming the tradition. And the wheel is simple and natural, but whole civilizations have developed to perfection without discovering it. The principles on which John Atanassov's computer was built, as much as we can see today, lie at the heart of the hundreds of millions of computers without which today's society can not exist. Every Bulgarian knows and is proud of the holy brothers Cyril and Methodius, whether the scripture of all Slavs through the Bulgarians. The Bulgarian blood donor John Atanasoff opened the way to the global information society. Academician Blagovest Sendov April 20, 2001
