The museums, the machines and the men and women who worked it out: laboratories kept as they were, beam engines under steam, the tunnel, the barrier, the roofs, and the plaques on the houses where the ideas came.

Where Lovelace wrote the notes of 1843 that described a computer program before there was a computer to run it.

Byron's daughter, brought up on mathematics by a mother determined she should not turn out a poet, lived in the square with her husband Lord Lovelace in the 1830s and 40s and wrote here the notes to her translation of Menabrea's account of Babbage's Analytical Engine - notes three times the length of the text, including an algorithm for the engine to compute Bernoulli numbers, and the observation that such a machine might one day compose music. The plaque is on the house; she died at thirty-six and is buried beside Byron.
