| RNDr. Zdenek Klein, 13.6.1944 – 4.9.2000 Zdenek Klein, a close friend of the Editor-in-Chief of the Neuroendocrinology Letters and The International Journal of the Prenatal and Perinatal Psychology and Medicine (where Zdenek was a member of the Editorial Board), suddenly and unexpectedly past away after a short and serious disease in Prague on September 4 of this year. He was one of the most faithful and greatest supporters of the Neuroendocrinology Letters in its transition during the last two years. He was one of the leading human ethologists in Europe, in particular in the Czech Republic and in the previous Czechoslovakia, with a rich record of scientific publications of both papers and books. One of his latest books, published in 1998 in Prague, was the Atlas of Semantic Gestures, which is one of the most outstanding works in this field. In his scientific approach he represented the integrative and transdisciplinary approach to the sciences combined with art, philosophy and poetry as it is also represented in the Neuroendocrinology Letters. Zdenek was teaching students of both the 3rd Medical Faculty and the Faculty of Natural Sciences at the Charles University of Prague. He was highly appreciated and loved by his students as well as his colleagues. He was a man of high personal integrity, decency, dignity and kindness, attributes which are seldom experienced in today’s world. All of us, who knew him closely and intimately, will miss him deeply. We have lost an indispensable friend, the scientific world has lost a noble personality, and the world has lost a great humanist. In this issue we are publishing a poster, one of his last scientific presentations planned and accepted for the International Conference of Psychology “Psychology After The Year 2000” at the University of Haifa, Israel, June 12–14, 2000, which he unfortunately never attended.
