'We know a lot about the US environmental movement. There is also a considerable body of scholarship that explores the tumultuous past of unions and unionizing. Forging the links between these historiographies has been rare. Add Empire of Timber to that clutch of pathbreaking studies.' Char Miller, Pomona College, California 'Empire of Timber represents a major contribution to environmental and forest history, and with its thoughtful thematic combination of work, health, and resource sustainability, it sits at the cutting edge of scholarship in these fields.' Sarah Phillips, Boston University
