In this archival investigation, Michael J. Michaud examines the life and work of Donald M. Murray, an important disciplinary and educational reformer who has for too long been misunderstood, caricatured, and dismissed by many writing studies theorists and historians. Focusing on Murray’s work at the University of New Hampshire from the 1960s to the 1980s, Michaud offers a corrective intended to establish a new legacy for Murray. Grounded in an understanding of the significance of his personal backstory to his reform efforts and narrated through the lens of a close reading of the day-to-day details of his work during the heady years of the writing process movement, A Writer Reforms (the Teaching of) Writing recounts the numerous innovations Murray contributed to composition pedagogy and traces the impact of his work on the growth of the field during a critical period in its development.
