Over the past two decades Thomas Fudge has established himself as one of the leading authorities on the early fifteenth-century Bohemian heretic-martyr, Jan Hus and the eponymous central European, pre-Reformation, religious reform movement,
Hussitism. In a steady stream of articles and monographs, Fudge has systematically mined the primary material (Hus's writings alone run to more than twenty-five volumes) and assimilated voluminous secondary and ancillary literature in Latin, Czech, and German.
