In 1843, Ada Lovelace imagined a machine capable of
extraordinary things, limited only by the creativity of its
programmernearly a century before the  rst computers
were built.
Ada was inspired by her colleague Charles Babbage’s
Analytic Engine. She saw Babbage’s engine as a machine
that could manipulate symbols in accordance with a set
of rules, but eloquently observed that the symbols could
extend well beyond numbers and equations:
The Analytical Engine weaves algebraic patterns just as the
Jacquard loom weaves  owers and leaves.
In collaboration with Babbage, she contributed step-by-step
instructions for how the machine could calculate a sequence
of Bernoulli numbers. In effect, this was the world’s  rst
published algorithm.
Ada imagined a device that could accomplish far more than
mathematics. She mused about its potential to compose 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 scienti c
pieces of music of any degree of complexity or extent.
We salute Ada Lovelace as computing’s visionary founder and
hope she’d be proud of the world she inspired.
