In fact, rather than having you run to your local library, I'll even find websites for you:this one notes the work that puts the virus in the 30's (I misspoke when I said 20's):http://www.ama-assn.org/special/hiv/newsline/cdc/020200g2.htmthis is the original NYT article:http://darwin.dsm.fordham.edu/ejs/bio/articles/020200aids-origin.htmlthis one tries to link HIV/SIV split around 300 years ago:http://www.ama-assn.org/special/hiv/newsline/cdc/112700g6.htmand there are innumerable sources that indicate the first recorded instances of infection were in the 50's. If you are interested in that aspect, feel free to search for "AIDS origins" or something of that sort.
