Career
David Alvarez devoted most of his life to teaching, particularly at Saint Mary's College of California where he is a professor emeritus now. He began his career at this university in 1973 becoming later a professor. In 1975 he was acting chair of the department of politics. In 1986-1991 and 1992-1993 he was chair of the department of politics.
During his years at Saint Mary's College of California, he was also a member of the Committee on Undergraduate Admissions and Financial Aid, Search Committee for the Dean of the School of Liberal Arts, Institutional Identity & Long-range Planning Subcommittee of WASC Self-Study, Faculty Programs Abroad Committee, Screening Committee for the Recruitment of an Academic Vice President, Rank and Tenure Committee, Steering Group of School of Liberal Arts, Academic Coordinating Committee, Academic Petitions and Standards Committee, Faculty Bookstore Committee, Faculty Development Committee, Faculty Grievance Committee, External Degree Programs Committee, President's Advisory Committee on Public Relations, Faculty Committee on the Academic Calendar, Committee on Lectures, Art, and Faculty Executive Committee.
At this college, he was also a member of the Advisory Board of Hearst Art Gallery, chair of the Faculty Programs Abroad Committee, and faculty representative to the Alumni Board of Directors. Alvarez was also a visiting professor in Italy and France.
A former scholar at the National Security Agency, David Alvarez emerged as a prominent historian of signals intelligence and other aspects of espionage, particularly as it was used in World War II. At the same time, he retained a strong early interest in the history of religion, and in two well-received books, he combined both of these interests by exploring the history of spying in the Vatican.
After editing An American Church: Essays on the Americanization of the Catholic Church and publishing a short work on United States-Turkish relations at the dawn of the Cold War, Alvarez edited Religion and Society in the American West: Historical Essays. According to the opening essay by Eldon G. Ernst, most historians of American religion have ignored the Far West, and historians of the Far West have neglected religion. The book sets out to correct that deficiency, covering numerous religious developments west of the Rocky Mountains, with sections on Missionaries, Education, Mormonism, and other sects and ethnicities that have shaped that history. It achieves a good balance between a broad picture, with articles on Mexican-American Catholicism and Judaism as civil religion, and more specific subjects dealing with individual personalities.
In Nothing Sacred: Nazi Espionage Against the Vatican, 1939-1945, Alvarez and coauthor Fr. Robert A. Graham explore another neglected area of religious history, the attempt by the Nazi regime to penetrate the legendary secrecy of the Vatican. Drawing on memoirs and newly available archives, the authors wrote a lucid and fascinating analysis of the Nazi attempts to understand Vatican strategies during World War II. According to Alvarez and Graham, those attempts seem to have been largely unsuccessful, foiled by the intense loyalty of ecclesiastics, the Nazis' pathological hatred for the Church, and bureaucratic infighting between various German agencies responsible for gathering information. This book contributes to the growing body of literature demonstrating the Vatican's importance in twentieth-century diplomatic affairs. Alvarez and Graham show the uniqueness of the Vatican and the difficulties any secular government had in penetrating an organization built on clerical loyalties and training in confessional secrecy.
Alvarez's next two books continued his interest in espionage during World War II. In Allied and Axis Signals Intelligence in World War II, Alvarez brings together a number of essays on collaboration within the alliances in the highly secretive area of codebreaking. Alvarez followed up with Secret Messages: Codebreaking and American Diplomacy, 1939-1945, a history of the origins of modern American signals intelligence. In it, Alvarez combined facts, careful history, intriguing and colorful personalities, and organizational detail into a well-written and captivating narrative.
In Spies in the Vatican: Espionage and Intrigue from Napoleon to the Holocaust, Alvarez returned to his longstanding interest in the attempts of largely secular nations to penetrate and influence the clerical world of the papacy. In some ways an easy target, due to its reliance on outdated codes and the ease of placing agents in this most cosmopolitan center, Alvarez shows that the Vatican has proven strangely resistant to the prying eyes of foreign governments, in part due to its strict hierarchy and the intense loyalty of its members to the interests of the Church. At the same time, he illustrates the frustrations of the Vatican in gaining worthwhile intelligence, due largely to its reliance on agents with religious, rather than intelligence, training, and its inability to keep up with European developments in spying technology.
