Translation and annotation of Luigi Menabrea's memoir on Babbage's Analytical Engine. These notes, three times longer than the original, constitute the first computer program in history and present the first algorithm intended to be executed by a machine.

The first algorithm ever written for a programmable machine, designed to compute Bernoulli numbers. This algorithm, inserted within the Notes, is considered the first computer program in history.

Intensive intellectual exchange between Ada and Babbage on the mathematical and mechanical principles of the Analytical Engine. This collaboration allowed Ada to develop her visionary understanding of the symbolic computation capabilities of machines.

Work on the application of mathematics to biological and neurological phenomena, demonstrating a pioneering approach to the mathematical modelling of complex natural systems.

Theoretical reflection integrated into the Notes on the abstract and universal nature of symbolic operations, anticipating modern concepts of programming and computational logic.

Comparative analysis between the punched card mechanism of the Jacquard loom and the programming principles of the Analytical Engine, establishing a conceptual lineage between textile automation and programmable computation.

The Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves. Here, we see the same principle applied to the results of arithmetical operations. [...] A new, vast, and powerful language will be developed for the purposes of mankind.

I am much annoyed at your having altered my Note. You know I am always willing to make any required alterations myself, but that I cannot endure another person to meddle with my sentences.

I have a peculiar way of learning. I require much rigid exactness in the demonstration or statement of principles, but I am remarkably quick in understanding difficulties when fully & clearly put before me.

That the Analytical Engine has no pretensions whatever to originate anything. It can follow analysis; but it has no power of anticipating analytical relations or truths.

Ada Lovelace's birthplace on 10 December 1815. It was in the British capital that she grew up and received her exceptional mathematical education, laying the foundations for her future scientific career.

Centre of mathematical excellence where Ada studied by correspondence with Augustus De Morgan, one of the greatest mathematicians of his time, who guided her intellectual development.

The place where Ada met Charles Babbage and learned about his Analytical Engine, a defining event that led her to develop her groundbreaking work on programming.

The workplace and site of collaboration between Ada and Babbage, where she translated and annotated documents on the Analytical Engine, producing the first computer algorithm in history.

A region in southern England where Ada spent part of her adult life. She took an interest in the technological and agricultural innovations of her era in this area.

A contemporary memorial institution where Ada Lovelace's legacy is preserved and celebrated, acknowledging her founding role in the history of computing and programming.

Mechanical prototype of a programmable calculator designed by Charles Babbage in the 19th century. Ada Lovelace worked on its specifications and wrote the first algorithm intended for this machine, thereby founding theoretical computer science.

Essential writing instrument in the 19th century for scholars and mathematicians. Ada Lovelace used quill and ink to draft her notes and her famous annotations on the Analytical Engine.

Medium for her mathematical work and detailed notes. Ada's manuscripts, in particular her notes on the Analytical Engine published in 1843, are foundational documents in the history of computing.

Characteristic garment of the Victorian era (1837–1901) worn by Ada Lovelace. A symbol of her time and of her position as a learned woman in a highly codified British society.

Graphical tools used by Ada to represent the sequential operations of the Analytical Engine. Her diagrams and tables are precursors to modern computing flowcharts.

19th-century educational resources used by Ada for her advanced mathematical training, which was rare for a woman of her era. Her exceptional education allowed her to understand and improve upon Babbage's work.

Prestigious object and symbol of the Victorian industrial age, emblematic of the precision and mechanics of the era. It represents the world of sophisticated machinery to which Ada theoretically contributed.
