EDITORS' ANNOUNCEMENT.

This article presents information on the contributions of editor Jonn L. Turk to the journal "Clinical and Experimental Immunology." Turk took the Journal over at short notice and under less than ideal circumstances. He worked energetically to build up its reputation for publishing first-rate papers both on medical immunology and on the more basic and experimental aspects. John's quiet but forceful style and his friendly persuasiveness with his scientific colleagues, attracted good papers for the journal and minimized publication problems and delays.
