RESIGNING. Henry Anatole Grunwald, 66, former editor in chief of Time Inc.; after two years as U.S. Ambassador to Austria. A native of Vienna who fled the Nazi take over in 1938, Grunwald strengthened ties with friendly Austria while keeping President Kurt Waldheim at arm's length. The journalist-turned-envoy, wrote Vienna's daily Standard, will be missed "as the son whom we drove out and to whom we owe so much."
