I have made my article on Turing's legacy available (see the attached pdf), since the publisher has now chosen to place it behind a firewall, and because I have retained my copyright.

One of my students at Utrecht University reflected during the spring of 2014 on the origins of computational complexity. She has given me permission to publish her beautiful essay here (anonymously).
Her chosen research topic is a difficult one to address. But, by presenting a pluralistic account in which she lets her historical actors tell the story (Cobham, Hartmanis, Rabin, Blum), she has succeeded in conveying technical information to an audience that need not be versed in complexity theory per se.
Towards a Historical Notion of "Turing — the Father of Computer Science" is Edgar Daylight's Original Manuscript of an article submitted for consideration in the journal History and Philosophy of Logic, copyright protected by E.G. Daylight.
