William Perkins was born in 1558 to Thomas and Hannah Perkins in the village of Marston Jabbett, in Bulkington parish, Warwickshire. As a youth, he indulged in recklessness, profanity, and drunkenness. In 1577, he entered Christ’s College in Cambridge as a pensioner, suggesting that socially he nearly qualified as gentry. He earned a bachelor’s degree in 1581 and a master’s degree in 1584.
While a student, Perkins experienced a powerful conversion that probably began when he overheard a woman in the street chide her naughty child by alluding to “drunken Perkins.” That incident so humiliated Perkins that he gave up his wicked ways and fled to Christ for salvation. He gave up the study of mathematics and his fascination with black magic and the occult, and took up theology. In time, he joined up with Laurence Chaderton (1536–1640), who became his personal tutor and lifelong friend. Perkins and Chaderton met with Richard Greenham, Richard Rogers, and others in a spiritual brotherhood at Cambridge that espoused Calvinist and Puritan convictions
