Answer:

This photosystem is known as PSI because it was discovered before photosystem II. Aspects of PSI were discovered in the 1950s, but the significances of these discoveries was not yet known.[4] Louis Duysens first proposed the concepts of photosystems I and II in 1960, and, in the same year, a proposal by Fay Bendall and Robert Hill assembled earlier discoveries into a cohesive theory of serial photosynthetic reactions.[4] Hill and Bendall's hypothesis was later justified in experiments conducted in 1961 by Duysens and Witt groups.
