Egil Krogh, Jr., was born in Chicago in 1939, the son of a Norwegian immigrant. After majoring in English at a small Christian Science college in southern Illinois, dropping out of business school at the University of Chicago, serving three years as a naval communications officer in the Pacific, and selling hats in a department store in Seattle, he finally graduated from the University of Washington Law School in June, 1968. Upon graduation, Krogh was offered an apprenticeship in the Seattle offices of John Ehrlichman, a long-time friend of Krogh's family; but he never had the opportunity to practice land-use law, as he had planned. in a few short months "Bud" Krogh followed Ehrlichman to Washington, where he was given the impressive-sounding title deputy counsel to the president, although in reality he was still Ehrlichman's personal assistant. Although Krogh had little experience in either government or politics (he had not even actively supported Nixon's quest for the presidency), Ehrlichman asked him to oversee the sensitive areas of federal law-enforcement and internal security matters. Before he had even turned thirty, Krogh thus found himself willy-nilly presiding over an unprecedented presidential law-and-order campaign. It was all a learning period, and he readily acknowledged his naivete to me in 1975, during a series of interviews.

John Strausbaugh [author of a previously published article about Christian Science]: I was born into Christian Science, and attended Principia College for four years... I always found it interesting that several of the Watergate perpetrators were Christian Scientists (Haldeman, Ehrlichman, Bud Krogh, e.g.).
