CHAPTER 01 · PERSON AND PERIOD
What questions surrounded Ada Lovelace?
Before the finished achievement, read what this person treated as a problem and where the surviving evidence reaches its limit.
A nineteenth-century mathematical writer who imagined what an unbuilt machine might do. After seeing Charles Babbage's Difference Engine in 1833, Ada Lovelace studied his plans for the Analytical Engine. In 1843 she translated Luigi Menabrea's article and added seven notes far longer than the original; Note G tabulated a procedure by which the unfinished Engine could calculate Bernoulli numbers. The Science Museum describes it as the first published algorithm and a document sometimes credited as the first computer program. The single label “first programmer” remains debated because of collaboration with Babbage and competing definitions of a program. Her clearer achievement was to see that a general machine could manipulate symbols, letters, or music as well as numbers — all while the machine itself remained unbuilt.
