Weber has been associated with the IHR since the 1980s. In 1992 he became editor-in-chief of the IHR's Journal of Historical Review. Weber was subsequently named the institute's Director in 1995.
Weber was born in Portland, Oregon in 1951. After graduating from Jesuit High School in 1969, he studied history in Chicago at the University of Illinois. He continued his studies for two semesters at the University of Munich, and, returning to Oregon, took a B.A. degree in history with high honors from Portland State University. In graduate school, he continued his study of history at Indiana University, receiving an M.A. degree in modern European history in 1977. Beginning in 1978 Weber became involved with the National Alliance, a far-right white supremacist organization. In 1979 Weber served as the editor of the group's magazine, the National Vanguard. Throughout the 1980s Weber functioned as the treasurer of the National Alliance's Cosmotheist Community Church, a pseudoreligious entity founded by William Luther Pierce. During this period Weber became more heavily involved with the IHR as well as collaborating with Bradley Smith and the Committee for Open Debate on the Holocaust (CODOH). In 2009, Weber wrote an article where he said that the IHR's efforts at Holocaust denial had been almost entirely ineffective, and as a result he was going to have the IHR focus on "Jewish-Zionist power" instead; many deniers were publicly furious with Weber because their efforts had been aimed at rehabilitating Nazism in general and Adolf Hitler specifically, and their general appreciation of anti-Israeli/Jewish groups that also espoused Holocaust denial (such as the Iranian government and Hezbollah) did not mean they wanted those groups to become the anti-Jewish vanguard instead of revived National Socialism.

- "While denial of the Holocaust's very occurrence had emerged already during the early postwar period, it gained new prominence in the 1980s and early 1990s. During this period denial attempted to leave the lunatic fringe and set out for the mainstream in both the United States and Europe, as figures such as Arthur Butz, Bradley Smith, and Robert Faurisson, together with organizations like the Institute for Historical Review, attempted to lend academic credibility to Holocaust Denial."
