Richard J. Jensen

In The Winning of the Midwest[13] Jensen tells a social history of elections in the Midwestern United States from 1888 to 1896. He analyzes the role religion played in political conflict, arguing that it had a major influence on party allegiances. Completed in 1966 as his PhD dissertation, the University of Chicago Press published it in 1971. Reviews in the Journal of the Illinois State Historical Society and The Journal of American History praised the work for its broad scope, prose style, and analysis.[14][15] A review in the Indiana Magazine of History criticised the work for attempting to tackle too broad a subject area and questioned Jensen's use of evidence to ascertain religious preferences.[16] It is his most widely cited work.[17]

In 1971 Jensen co-authored the Historian's Guide to Statistics with Charles Dollar. The book became one of the most widely used guides to interpreting historical statistics.[18]

In 1978 Jensen's Illinois: A Bicentennial History was published by Norton, New York in its States and the Nation series. The work presents Illinois' history as that of a conflict between the state's original traditionalist settlers and later modernist immigrants. In a 1979 book review in the Indiana Magazine of History, Martin Ridge praised the work for having a higher level of academic rigor than the other books of the series. While recommending it as "in many ways [...] the best interpretative one-volume state history around," he claimed that its arguments are ultimately "unconvincing."[19] Writing in the Journal of the Illinois State Historical Society John Hoffman described the work as "a balanced account of the state, keeping Chicago in proportion to downstate, and the whole in alignment with American history—as 'a' microcosm of the Union, not 'the' microcosm...his Illinois is not Chicago writ large or America writ small. For state history, that is no mean achievement.[20]

H-Net, short for "Humanities & Social Sciences Online", is an interdisciplinary forum for scholars in the humanities and social sciences. It began in 1992 as an initiative by Jensen at the History department at the University of Illinois at Chicago to assist historians "to easily communicate current research and teaching interests; to discuss new approaches, methods and tools of analysis; to share information on access to library catalogs and other electronic databases; and to test new ideas and share comments on current historiography."[21] The network grew rapidly, growing from approximately 6,000 subscribers in 1993 to more than 51,000 by 1997.[3]

In 1997 H-Net won the American Historical Association's James Harvey Robinson Prize, awarded for innovative methods of history teaching.[22] According to the historian Paul Turnbull, under Jensen's leadership—and with funding from the National Endowment for the Humanities—H-Net "rapidly became a forum attracting both historians with established expertise in computer-based quantitative research and younger colleagues interested in exploring the analytical possibilities of hypertext," and "greatly assisted the development of the technical expertise and intellectual ambitions of historians who undertook a remarkable number of Web-based projects through the second half of the 1990s."[18]

In 1994, H-Net began a move to Michigan State University, where historian Mark Kornbluh had secured institutional support.[23] In 1997, Kornbluh and Jensen competed against each other in a "bitterly contested" election for the position of H-Net's executive director, with Jensen arguing that H-Net should be decentralized while Kornbluh advocated consolidation the organization's operations at Michigan State.[24][25] Kornbluh ultimately won the support of the editors of H-Net's discussion lists.[25]

1909 newspaper article concerning "No Irish Need Apply" help-wanted advertisement

Jensen's article about anti-Irish sentiment, "No Irish Need Apply: A Myth of Victimization", was published in the Journal of Social History in December 2002. It argues that "No Irish Need Apply" (NINA) signs were mostly a myth, and that there was "no significant discrimination against the Irish" in the US job market.[26] In July 2015, the same journal published a rebuttal to Jensen's thesis written by Rebecca Fried, an eighth-grade student at Sidwell Friends School, Washington, DC.[27][28][29] Before submitting her article for publication, Fried consulted with the historian Kerby A. Miller, who had long disagreed with Jensen's thesis. Miller found her argument to be a worthy, scholarly rebuttal in need of little editing.[27] Fried's paper provided examples of "No Irish Need Apply" in newspaper archives, contesting Jensen's thesis that there was no evidence of the same.[28] The following month, Jensen wrote a rebuttal to her argument for the History News Network.[30]
