Laboratory Astrophysics in Leiden was established in 1975 by prof. J. Mayo Greenberg. After prof. Greenberg's retirement in 1992, the laboratory came under the direction of prof. Ewine F. van Dishoeck and its research was integrated with that of the astrochemistry group in Leiden and elsewhere in the Netherlands. Permanent support for the operation of the laboratory was secured in 1998 through generous grants from Raymond and Beverly Sackler and the Netherlands Research School for Astronomy (NOVA).
