Joseph Smale (1867-1926) was one of the central figures involved in the chain of events leading to the 1906 Azusa Street Revival in Los Angeles. This study presents the diverse infl uences which impacted Smale - formative years in Britain, growing up in Cornwall and Somerset amid a rhythm of Wesleyan revival; Reformed theological training under the tutelage of C.H. Spurgeon in London; migration to the United States; plus hard experiences in the 'school of anxiety' - which were all precursors for Smale's influential role as champion of Pentecostal revival. Smale's leadership will resonate with every church leader who prays for revival and longs for more Holy Spirit power experimentally. Furthermore, his story is also educative for those contending with some of the more problematic and 'untidy' aspects of Pentecostal-Charismatic experience, involving painful power struggles, hurts, abuse of freedom, spiritual excesses and so on. Smale's 'Moses' designation and biography still have relevance for the church in the present day.
