Though a number of missionaries came before him and though the Pentecostal experience took place in India independent of foreign missionary work, Cook was the one that first established works that began to spread into neighboring areas. He came to India in October 1913. In 1914, he established a church in Thuvayoor, Kerala. However, three years later, on August 31, 1917, his wife, Anna, died. The following year, he met and married Bertha Frank.
