Who Invented the Computer History
There are a lot of questions in your head. You might wonder who invented the computer. Luckily, this article will answer all of your questions! We’ll take a look at the Atanasoff-Berry Computer, the inventor of the first electronic computer, Herzstark and Napier, and Turin, the inventor of computer science. We’ll also touch on how the computer was first used in the U.S.
Atanasoff-Berry Computer was the first truly electronic computer
The Atanasoff-Berry Computing System was built in 1942. It used electronic binary logic, a combination of transistors and vacuum tubes, and dynamically refreshed capacitors for memory. It was capable of 30 simultaneous operations, and fewer parts than a serial computer. It was designed by John Vincent Atanasoff and Clifford E. Berry, and was the first fully electronic computer ever constructed. The Atanasoff-Berry Computer was dismantled and rebuilt at Iowa State University/Ames Laboratory in 1994. It was completed in October of that year.
The Atanasoff-Berry Computing System was a step-up from previous calculating machines, which required the operator to set up and adjust their functions. Its functions were similar to those of unit record equipment and electro-mechanical calculators. An operator would select the operation they wanted the machine to perform by selecting front-panel switches. It was capable of calculating and reducing equations up to ten digits.
Inventor John Vincent Atanasoff was born in Osteen, Florida, and later graduated from Iowa State College. He began learning about electricity when he was nine years old. His mother taught in Montana until 1929, and they moved back to Ames. John Vincent Atanasoff earned his doctorate in theoretical physics at the University of Wisconsin in Madison. His thesis concerned the electrical properties of helium. He spent weeks calculating the equations for his final thesis using a desk calculator.
Napier invented logarithms
Before Napier invented logarithms, there were many other inventors of these mathematical concepts. These included Justus Byrgius and Henry Briggs. Byrgius was an accomplished mathematician who was also an inventor of the difference machine. His work is also remembered as the inventor of Napier’s Bones, a set of rods that contained tables for multiplication and division. The user could select the right rod for the particular multiplication they needed and then add up the partial products. He even invented the cube root.
The abacus is an ancient mathematical device consisting of a series of beads divided into two parts. Each digit is represented by an appropriate place on the abacus. Napier used this method to simplify calculation by finding a relationship between two different number series. The resulting number is known as the “logarithm”. It is possible to perform both addition and subtraction by multiplying it by a constant factor.
John Napier was a Scottish nobleman and politician who studied mathematics in his free time.
He was particularly interested in using logarithms as a tool to simplify computations. His logarithms were made possible by incising logarithmic measurements on wooden rods. These logarithmic measurement rods became known as Napier’s Bones. Until now, many students have simply memorized the rules for logarithms without understanding the concept behind them.
Herzstark invented sliderule
In 1947, a German named Paul Herzstark invented the first computer. The sliderule was a calculator that resembled a tin can and weighed 230 grams. It had four functions – addition, subtraction, multiplication, and division. It also had a keyboard and an automatic divider device. It had a smooth crank handle on top and was capable of performing all four basic operations, including square roots.
In 1924, Herzstark began studying mechanical engineering in Vienna. He then returned to his family’s factory in Vienna. His father, Samuel Herzstark, had sent him to reorganize the sales organization in Hungary and Czechoslovakia. By 1928, Herzstark had made his first invention, a
multi-summator, which added horizontal and vertical columns in a calculating mechanism.
Herzstark’s invention quickly became an instant hit in Berlin.
In the summer of 1943, two workers at the Herzstark factory were arrested by the Gestapo for listening to the English radio and duplicating messages using a typewriter. One of them, Curt, was half-Jewish and had fled the factory. He was taken to Buchenwald concentration camp and imprisoned for his political views. Despite this tragic end, Herzstark continued to work and he invented the sliderule.
Turin invented computer science
Alan Turing invented computer science in 1934. Computer science was once only a domain of enthusiasts and scientists. However, it entered a new era in the 1970s and 1980s, when companies like Xerox, IBM, Apple, and Microsoft realized the immense potential of the new technology. With the advancement of computing technology, it became possible to develop computer applications within a few days. Today, you do not need to know any programming language to develop computer applications.
Copeland, a philosopher, approached the history of computing in the 1940s from a different perspective. He believes that the Turing claim is based on the recollections of a former lecturer. Moreover, the British military used Colossus computers to crack codes during the war, and so it is wrong to assume that Turing was the designer of the machine. The Colossus computer was actually designed by someone else.
In the early years of computer science, Turing was not involved in professional groups, did not edit journals, did not direct a large cohort of future computer scientists, and never built a computer lab or degree program. Turing did not win any major grants. Moreover, he does not appear among the organizers of early computing symposia. This suggests that Turing’s interests had already strayed away from such early concerns.
Zuse’s Z3 calculator
It was the German inventor Konrad Zuse who invented the computer. Zuse worked in the Henschel airplane factory in Berlin. There he developed S1 and S2 machines, which were capable of automatically measuring the wing parameters of missiles. The machines turned analog measurements into digital values, and they computed corrections to the wing based on those values. However, these machines were inconvenient for the average worker because they required typing numbers into a decimal keyboard. Despite the Z3’s revolutionary nature, the machines were never used in real production.
In 1938, Zuse constructed the first programmable mechanical computer. In Berlin, he built three electronic models before 1949, including the Z3 calculator. The Z-series devices continued to develop and Zuse eventually developed the Graphomat Z64 punch-card-controlled plotter. Despite Zuse’s early success, his work was little known outside Germany. In the years following, he would become famous outside of Germany, establishing the world’s first computer museum.
As a result, Zuse’s Z3 had no impact on computing outside Germany. A replica of the Z3 is on display in the Deutsches Museum in Munich. Its design is largely unknown outside of Germany, but it did impact the development of computing in that country. Its influence on the rest of the world was limited to the military’s needs. But Zuse was not content with this and continued to develop his work, until he was called to military service in 1945.
ENIAC was the first multipurpose electronic computer
The history of the ENIAC goes back to World War II. During the war, artillery units used tables to estimate trajectory and had to calculate variables manually. John Mauchly and John Presper Eckert, graduate students from the University of Pennsylvania’s Moore School of Electrical Engineering, set out to develop a computer that could do the same tasks. The result was the ENIAC, which was the first multipurpose electronic computer.
In 1945, the Electronic Numerical Integrator and Calculator (ENIAC) was completed. It was the first multipurpose electronic computer, and it broke speed records in its day. Today’s laptops can do 500 million additions in one second. However, the ENIAC was so big and bulky that it led to power shortages in Philadelphia. However, it did make math easier.
The original ENIAC had a few weaknesses. Its primitive read-only-storage programming mechanism used function tables as ROM and required programming by setting switches. But after 1947, improvements were made to the ENIAC. The ENIAC’s instruction set was also revised. The accumulators in ENIAC used two tubes as flip-flops and could perform 5,000 operations per second.
Zuse co-founded Apple Computer
In 1938, German-born Konrad Zuse invented the first programmable, digital computer. In the kitchen of his parents’ apartment, Zuse built his first computer, the Z1. It featured a keyboard and flashing lights for input and output. Today, an authentic Z1 is on display at the German Museum of Technology, which has an entire section dedicated to the founder. The Deutsches Museum in Berlin also displays an original Z3 and replica Z4.
Steve Wozniak and Zuse were high school classmates, and they met when Jobs was at a computer conference. They decided to quit their jobs at Hewlett-Packard and start their own company. The two worked out of their family garage, attempting to produce a more user-friendly computer. Zuse did the research and development, while Wozniak honed his engineering skills.
Steve Wozniak was a successful investor in various startups. In 1986, he founded CL-9, a company that made the first universal remote control. And in 2002, he cofounded Wheels of Zeus, a company that aimed to create wireless GPS technology. In addition to his successful business career, Wozniak also has a number of other ventures.
