Note G [a] is a computer algorithm written by Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine.
Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852), also known as Ada Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications ...
Ada Lovelace was the first person to publish an algorithm intended to be executed by the first modern computer, the Analytical Engine created by Charles Babbage. As a result, she is often regarded as the first computer programmer. [9] [10] [11] Lovelace was introduced to Babbage's difference engine when she was 17. [12]
The first known computer algorithm was written by Ada Lovelace in the 19th century for the Analytical Engine, to translate Luigi Menabrea's work on Bernoulli numbers for machine instruction. [3] However, this remained theoretical only - the lesser state of engineering in the lifetime of these two mathematicians proved insufficient [ citation ...
Lovelace, Ada: An English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognize that the machine had applications beyond pure calculation, and created the first algorithm intended to be carried out by such a machine.
Lovelace's note G on the Analytical Engine (1842) describes an algorithm for generating Bernoulli numbers. It is considered the first algorithm ever specifically tailored for implementation on a computer, and thus the first-ever computer programme. [11] [12] The engine was never completed, however, so her code was never tested. [13]
Lovelace designed the first algorithm intended for processing on a computer, Babbage's analytical engine, which is the first device considered a real Turing-complete computer instead of just a calculator. Although the full implementation of Babbage's second device was not realized for decades after her lifetime, Lovelace has been called ...
Among his notable publications: Sketch of the Analytical Engine Invented by Charles Babbage, Esq. with notes by translator Ada Lovelace (1842), which described many aspects of computer architecture and is considered the first modern example of programming. Both are available on Wikisource: The Menabrea article; The notes by Ada Lovelace.
