Ada Lovelace - First Computer Program

First Computer Program

In 1842 Charles Babbage was invited to give a seminar at the University of Turin about his analytical engine. Luigi Menabrea, a young Italian engineer, and future Prime Minister of Italy, wrote up Babbage's lecture in French, and this transcript was subsequently published in the Bibliothèque Universelle de Genève in October 1842.

Babbage asked Ada to translate Menabrea's paper into English, subsequently requesting that she augment the notes she had added to the translation. Ada spent most of a year doing this. These notes, which are more extensive than Menabrea's paper, were then published in The Ladies' Diary and Taylor's Scientific Memoirs under the initialism "AAL".

In 1953, over one hundred years after her death, Ada's notes on Babbage's Analytical Engine were republished. The engine has now been recognised as an early model for a computer and Ada's notes as a description of a computer and software.

Ada's notes were labelled alphabetically from A to G. In note G, she describes an algorithm for the analytical engine to compute Bernoulli numbers. It is considered the first algorithm ever specifically tailored for implementation on a computer, and for this reason Ada is often cited as the first computer programmer. However the engine was not completed during Lovelace's lifetime.

    Family life is not a computer program that runs on its own; it needs continual input from everyone.
    Neil Kurshan (20th century)

    The computer takes up where psychoanalysis left off. It takes the ideas of a decentered self and makes it more concrete by modeling mind as a multiprocessing machine.
    Sherry Turkle (b. 1948)

    These native villages are as unchanging as the woman in one of their stories. When she was called before a local justice he asked her age. “I have 45 years.” “But,” said the justice, “you were forty-five when you appeared before me two years ago.” “Señor Judge,” she replied proudly, drawing herself to her full height, “I am not of those who are one thing today and another tomorrow!”
