How was hiv/aids discovered and when was the first person with hiv identified?

Long story, but...: In short, HIV was discovered by 2 groups (lav in 1983 - dr. Montagnier and HTLV-III in 1984 - dr. Gallo) in separate labs. Later in 1985, these were found to be the same virus, named hiv. The aids epidemic officially began on 6/5/81 after the cdc reported unusual cases of pcp pneumonia in 5 gay men in los angeles. In retrospect, the earliest cases of HIV have been traced back to around 1959.
