I also strongly recommend the excellent 1988 paper by Robin Gandy, The Confluence of Ideas in 1936, published in The Universal Turing Machine A Half-Century Survey (ed. Rolf Herken), 1995[1] (pp. 51-102).
Gandy gives a full historical background of who knew what in 1936, what the general state of knowledge was at the time, and the reception of both Church's and Turing's papers.
