I am looking for some core texts (books, book chapters, papers) about the general history of contemporary combinatorics, starting, say, from the interwar period up to today.

Texts about the history of computer science & the theory of computation might be ok, but I guess I want to focus more on the general history of the 'pure' mathematics side.

Most of the main works I have found so far seem to talk about the earlier periods. I am familiar with some of Gian-Carlo Rota, Timothy Gowers and Terence Tao's expository pieces, and also the many biographies of Paul Erdos. I am also familiar with Norman Biggs and Edward Brian Davies's work.
