Stephen Shadegg

Mr. Shadegg was active in politics for more than four decades and helped elect many influential figures to public office in Arizona. As Mr. Goldwater's campaign manager in 1952, he helped the former department-store executive upset Ernest McFarland, the Senate Democratic leader, to win the first of five terms in the Senate. Mr. Shadegg had been a registered Democrat and once served as campaign manager for Senator Carl Hayden of Arizona, a Democrat who served more than 50 years in the Senate. In 1962, by then a Republican, Mr. Shadegg let Senator Goldwater persuade him to run in the Republican primary for the seat held by Senator Hayden. Mr. Shadegg lost to Evan Mecham, later Arizona's Governor, in a bitter contest in which Senator Goldwater was publicly neutral. Mr. Shadegg later said he had felt ''terribly let down'' by the Senator's stance. Mr. Shadegg, born in Minneapolis, was also a freelance writer who wrote more than 500 stories for detective magazines. After moving to Arizona in 1937 he wrote radio scripts and later spent two years in Hollywood writing scripts for RKO Pictures. But politics became his passion and he managed more than 40 campaigns for local, state and national offices. Mr. Shadegg's wife, the former Eugenia Kerr, died two years before him. He is survived by two sons, Stephen of Tucson and John of Phoenix; and two daughters, Cynthia Ackel of Tempe and Eugenia Johnson of Phoenix.
