Professor Wolfgang Walter in memoriam

“…Several papers appeared in the 1950s, which dealt for instance with the synthesis of amino acids [2] and their detection and identification in proteins [3]. In 1957, the famous experiments of S. Miller and H. C. Urey on the formation of organic compounds by electric discharges in atmospheres of simple gases were reproduced and confirmed in Hamburg.…”
