Abba J. Kastin, the Zeitgeist, and the inception of Peptides.

It is wonderful to be able to record the establishment and growth of a professional journal after thirty-five years, and to celebrate the splendid career of Abba J. Kastin as an editor as well as a scientist and educator. Abba is also an enriched human being who is both sophisticated and simple, and we are proud to be life-long friends of his.
