Who invented the binary decimal system?

Answer 1

I don't believe anyone suggested it, certainly no-one that could be named at least. Long before we had digital computers we had machines that were fully capable of processing binary information. The Jacquard loom is a prime example which pre-dates Charles Babbage's early computer designs. Although Babbage dabbled with decimal machines, even he saw the benefits of using binary; by far the simplest method of implementing a numeric system at the machine level.

Answer 2

Binary numeral system - History The ancient Indian mathematician Pingala presented the first known description of a binary numeral system in the 3rd century BC, which coincided with his discovery of the concept of zero. The modern binary number system was fully documented by Gottfried Leibniz in the 17th century in his article Explication de l'Arithmétique Binaire. Leibniz's uses 0 and 1, like the modern binary numeral system. In 1854, British mathematician George Boole published a landmark paper detailing a system of logic that would become known as Boolean algebra. His logical system proved instrumental in the development of the binary system, particularly in its implementation in electronic circuitry. In 1937, Claude Shannon produced his master's thesis at MIT that implemented Boolean algebra and binary arithmetic using electronic relays and switches for the first time in history. Entitled A Symbolic Analysis of Relay and Switching Circuits, Shannon's thesis essentially founded practical digital circuit design. In November of 1937, George Stibitz, then working at Bell Labs, completed a relay-based computer he dubbed the "Model K" (for "kitchen", where he had assembled it), which calculated using binary addition. Bell Labs thus authorized a full research program in late 1938 with Stibitz at the helm. Their Complex Number Computer, completed January 8, 1940, was able to calculate complex numbers. In a demonstration to the American Mathematical Society conference at Dartmouth College on September 11, 1940, Stibitz was able to send the Complex Number Calculator remote commands over telephone lines by a teletype. It was the first computing machine ever used remotely over a phone line. Some participants of the conference who witnessed the demonstration were John Von Neumann, John Mauchly, and Norbert Wiener, who wrote about it in his memoirs.

Answer 3

Either:

• Konrad Zuse in Germany, his Z1 used binary floating point (no integers) numbers, but was completely mechanical.
• John Vincent Atanasoff in Ames, Iowa US, his ABC used 50 bit binary numbers.

Both were just before WW2.

Answer 4

Gottfried Wilhelm von Leibniz (1646-1716) refined the binary number system, which is at the foundation of virtually all digital computers. Although the binary computer did not exist in his time, Leibniz philosophized about a computer based on a binary numerical system. In 1679 he wrote, "Despite its length, the binary system, in other words counting with 0 and 1, is scientifically the most fundamental system, and leads to new discoveries. When numbers are reduced to 0 and 1, a beautiful order prevails everywhere."

The origins of the binary system itself can be traced back to ancient civilisation. The Sumerians were using sexagesimal (base 60) over 5,000 years ago, so it stands to reason they were quite familiar with all other bases, including binary. Base 60 was the base of choice back then because of its high divisibility (divisible by 2, 3, 4, 5 and 6). We still use it today to tell the time (60 seconds, 60 minutes, 24 hours) and is also the reason circles have 360 degrees.

Frank Gray

Correction: Frank Gray (1887-1969) was born 171 years after Leibniz' death. He patented Gray Code, a reflected binary code which "may be built up from the conventional binary code by a sort of reflection process", but he did not come up with the idea of using binary code to store programs. Gray Code is not, in fact, used in binary computers for the purpose of data storage of any kind. It is primarily used to facilitate error correction in digital communications such as digital television.

Answer 5

Joseph Marie Jacquard (1752-1834) is credited as the first "binary programmer", although his machine was a programmable loom (the Jacquard Loom) rather than a computer.

Answer 6

Gottfried Wilhelm Leibniz.
