May, J. Peter An appreciation of the work of Samuel Eilenberg (1913–1998). (English) Zbl 1276.55001 Wiadom. Mat. 48, No. 2, 185-197 (2012). From the text: It is impossible to do justice to Sammy’s (as he was known in the world of mathematics) entire output, and I’ll focus on that part of his work which I know best, mixing a chronological development with a thematic one. Thus I will consider the earliest paper on each theme, no matter how relatively inconsequential, and then briefly trace the development of that theme chronologically as it evolved to give the full flowering of the theme, very often in essentially the same form that we know it today, in all cases roughly a half century later. Since the themes were thoroughly intermingled, this cannot do justice to Sammy’s work, but it is the best I can do.
