Happy Birthday To Ada Lovelace, the First Computer Programmer

First time accepted submitter MrBeeudoublez writes "Honored by a Google Doodle, Ada Lovelace is the first computer programmer. From the article: 'Ada's life as a member of British society (first as the daughter of Lord Byron, and later as the wife of the Count of Lovelace), brought her into contact with Charles Babbage, whose concepts for mechanical calculating machines (early computers) she took a great interest in. Ultimately, her work on explaining Babbage's design for the Analytical Engine resulted in her being credited as the first true computer programmer in history, even if the computer she programmed for was not actually built until 2002.'"

The first programmer was Hero of Alexandria

[Anonymous Coward]

According to Wikipedia, the ancient Greek mathematician invented "a programmable cart that was powered by a falling weight. The "program" consisted of strings wrapped around the drive axle."

This doesn't diminish Ada Lovelace's contributions at all, btw.

Perhaps this *will* diminish Ada's contributions: http://www.answers.com/topic/ada-lovelace#Controversy_over_extent_of_contributions Choice quote: "Not only is there no evidence that Ada ever prepared a program for the Analytical Engine but her correspondence with Babbage shows that she did not have the knowledge to do so." The depressing lack of female role models in CS is a real problem, but revisionist history is not a valid solution.

I think we have to differentiate between a purely sequential program and one that can make decisions. For example in Lovelace's time automatic looms that were programmed with reels of punched paper existed, but they could only produce a fixed pattern from start to finish.

Such looms, along with mechanical pianos, mechanical dolls and Hero's cart are not computers. They are fixed function and their programs cannot respond to inputs. Lovelace was the first computer programmer.

Props to Hero for inventing the vending machine though.

Well, there's certainly a shortage, but I don't think anyone can deny Rear Admiral Grace Hopper's contributions to software engineering. Her contributions had a direct influence on how programming languages evolved.

I'm not so sure about this.
From "The Information", by Gleik:
Her exposition took the form of notes lettered A through G, extending to nearly three times the length of Menabrea’s essay. They offered a vision of the future more general and more prescient than any expressed by Babbage himself. How general? The engine did not just calculate; it performed operations, she said, defining an operation as “any process which alters the mutual relation of two or more things,” and declaring: “This is the most general definition, and would include all subjects in the universe.” The science of operations, as she conceived it,
"is a science of itself, and has its own abstract truth and value; just as logic has its own peculiar truth and value, independently of the subjects to which we may apply its reasonings and processes. One main reason why the separate nature of the science of operations has been little felt, and in general little dwelt on, is the shifting meaning of many of the symbols used."

Symbols and meaning: she was emphatically not speaking of mathematics alone. The engine “might act upon other things besides number.” Babbage had inscribed numerals on those thousands of dials, but their working could represent symbols more abstractly. The engine might process any meaningful relationships. It might manipulate language. It might create music. “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.”

It had been an engine of numbers; now it became an engine of information. A.A.L. perceived that more distinctly and more imaginatively than Babbage himself. She explained his prospective, notional, virtual creation as though it already existed:
"The Analytical Engine does not occupy common ground with mere 'calculating machines'. It holds a position wholly its own. A new, a vast, and a powerful language is developed in which to wield its truths so that these may become of more speedy and accurate practical application for the purposes of mankind than the means hitherto in our possession have rendered possible. Thus not only the mental and the material, but the theoretical and the practical in the mathematical world, are brought into more intimate and effective connexion with each other."

A particularly sloppy summary

[ngibbins]

Lovelace's contribution lay in her translation and annotation of Menabrea's description of the Analytical Engine, for which she wrote a short program. Like the Difference Engines, the Analytical Engine was not built during Babbage's (or Lovelace's) lifetime. Unlike the Difference Engine, the Analytical Engine has never been built; the "computer [...] not actually built until 2002" was the Difference Engine No.2, designed by Babbage in the late 1840s, which is a calculator and not a computer. The date of 2002 is also misleading, and refers to the completion of the printer for the DE No.2 (in 2000) that was built by Doron Swade's group at the Science Museum in London between 1989 and 1991. Furthermore, her husband was not the "Count of Lovelace", but rather the 1st Earl of Lovelace (formerly Lord King, Baron of Ockham, and then Viscount Ockham). 'Count' is not a British title of peerage; her title of countess was therefore the result of her marriage to an earl.
