In ESO period 65 (April–September 2000) the large programme 165.N-0276, led by Roger Cayrel, began making use of UVES at the Kueyen VLT telescope. Known within the Team and outside as “First Stars”, it was aimed at obtaining high resolution, high signal-to-noise ratio spectra in the range 320 nm–1000 nm for a large sample of extremely metal-poor (EMP) stars identified from the HK objective prism survey [T.C. Beers, G.W. Preston, S.A. Shectman in Astron. J. 90, 2089 (1985); T.C. Beers, G.W. Preston, S.A. Shectman in Astron. J. 103, 1987 (1992)]. The goal was to use these spectra to determine accurate atmospheric parameters and chemical composition of these stars which are among the oldest objects amenable to our detailed study. Although these stars are not the first generation of stars they must be very close descendants of the first generation. One may hope to gain insight on the nature of the progenitors from detailed information on the descendants.
