Blaauw A. , ESO's early history: The European Southern Observatory from concept to reality (Garching bei München, 1991). This excellent book is the source for much of the section on ESO; however, Dr Blaauw was naturally not aware of Oort and Baade's earlier discussion of this concept.

Babcock H. W. Beckers J. M. , 22 Jan. 1993. I am greatly indebted to Dr Babcock for telling me of his recollection, and sending me a copy of this letter. He thought their conversation was “in 1953 (or possibly in the preceding year)”; since Oort was not in Pasadena in 1953 but was for nearly three months in early 1952 it must have been then. At least partial corroboration is in WB to [JH]O, 14 Oct. 1957, ULL, a retrospective letter Baade wrote after learning from Oort that the ESO project would go ahead. In it Baade said he was enthusiastic as he was when they discussed it on the automobile trip from Amsterdam (when Baade arrived by air in May 1953) through the tulip fields to Leiden. Its seems unlikely that this topic would have come up spontaneously under those circumstances, but quite natural if Oort were reminding Baade of their early discussion, and telling him that now was the time to go ahead with it.

At midnight on 30 June he, Whitford Albert E. , who at that same instant was officially transferring from the University of Wisconsin faculty to the University of California (as director of Lick Observatory), and I, moving from Caltech to Wisconsin (as an assistant professor), were talking over a few quiet glasses of beer in Baade's motel near the campus.
