The eleventh monograph and meeting of the Foundation on "Hormon­ al Control of the Hypothalamo-Pituitary-Gonadal Axis" was held in October 1983 at the Weizmann Institute of Science. This monograph honors the memory of Professor Hans R. Lindner, a productive and innovative scientist greatly respected and admired by his col­ leagues. When addressing the opening session I remarked that my impres­ sion of the Weizmann Institute was one or two large buildings hous­ ing the various departments. This was my first visit to Israel and I was overwhelmed by the beautiful semi-tropical gardens of the in­ stitute, in a setting of shrubs and trees, orange groves and flow­ ers. Sited among this seventy-five acres are over fifty buildings and residential areas for the staff and visiting scientists. I saw pictures of this area when Dr. Chaim Weizmann founded in 1934, the Daniel Sieff Research Institute, the forerunner of the Weizmann In­ stitute. The site was sand dunes without a blade of grass. That the desert shall bloom is illustrative of the progress made in Is­ rael. The topics of the monograph are grouped into twelve sections.
