This edited collection of essays brings together scholars across disciplines who consider the collaborative work of John Matthews Manly and Edith Rickert, philologists, medievalists and early modernists, cryptologists, and education reformers. These pioneers crafted interdisciplinary partnerships as they modeled and advocated for cooperative alliances at every level of their work and in all their academic relationships. Their extensive network of intellectual partnerships made possible groundbreaking projects, from the eight-volume Text of the Canterbury Tales (1940) to the deciphering of the Waberski Cipher, yet, except for their Chaucer work, their many other accomplishments have received little attention. Collaborative Humanities Research and Pedagogy not only surveys the rich range of their work but also emphasizes the transformative intellectual and pedagogical benefits of collaboration.
