Ada Lovelace (1815-1852) is considered as the first programmer in the history of computer science, even before the existence of this discipline. She had discovered and was fascinated by the “Babbage difference machine”, a kind of gigantic calculating machine. But she had, from this, conceived modes of operation, founders of computer science, which largely exceeded the machine itself. It could not implement them concretely.
Babbage’s machine was designed to do only one type of calculation. Ada Lovelace conceptually extended the possibilities by proposing that a computing machine could be universal, i.e. could perform all types of operations, on all types of objects. Ada Lovelace did not only dream about the universality of computing, she also proposed technical solutions, namely :
Ada Lovelace’s concepts have largely inspired John Von Neumann, and many others. They are the basis of the logic of current computer science, as well as its uses. She wrote for example “The machine could compose refined and scientific pieces of music of any degree of complexity”, prefiguring without knowing it the logics and fields of application of artificial intelligence.
Ada Lovelace was the daughter of the poet Lord Byron who initiated, the year of Ada’s birth in 1815, a “writing workshop” with several of his friends, which gave birth to Mary Shelley’s Frankenstein, the first occurrence of the idea of a humanoid created by man, which escapes him... It is astonishing that it is his own daughter who will lay major stones of the future science which will allow, two centuries later, the real manufacture of the intelligent robot which will free itself from the human.

“The operating mechanism can even be thrown into action independently of any object to operate upon (although of course no result could then be developed). Again, it might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine. Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.”
Ada Lovelace, 1842.
