Where can I find historical discoveries and contributions in the history of surgical asepsis?”
I don’t know what kind of research you are doing and for what purpose (or if it’s only for personal reading) so I don’t know what kinds of books to recommend. However, if you just need a layman’s explanation of the origins and major discoveries in asepsis, I highly recommend this book: Century of the Surgeon by Jurgen Thorwald [Pantheon Books (1957)] Don’t let the early publication date scare you away, because most of the important discoveries in asepsis were made before that date. This book is actually a history of surgery in the approximately 100 years from the 1850s to the 1950s and although all of the facts used are historically accurate and quite explanatory, the author uses the device of having one fictional narrator explain all the discoveries (and the history before we knew much) as though most of them happened during his lifetime. He injects himself into the history, but doesn’t change the historical events in any way other than saying that he was there for many of the events.
