The civic, intellectual, and epistemological rehabilitation of Marc Bloch's reputation invites a deeper look at the author of Strange Defeat as a scholar, professor, and citizen. This biography shows how Bloch's intellectual approaches – the "regressive method," comparative history, the history of social structures —his vision of how history should be taught, and his political commitments as a chitizen were informed by the same questionings. It also demonstrates how his desire for cross-pollination among the various forms of interventions that historians practice proved unfruitful yet ultimately generative.
