Thomas Grantham (1633/341692) provided important leadership as an English nonconformist and General Baptist polemicist and messenger in the second half of the seventeenth century. Grantham was baptized around 1652 in the Baptist church at Boston, Lincolnshire, and became one of the most significant Baptist figures of the period, yet no major historical study of Grantham has appeared until now. John Inscore Essick is assistant professor of Church History at the Baptist Seminary of Kentucky in Georgetown, Kentucky. He holds degrees from Appalachian State University (BS), Campbell University Divinity School (MDiv), and Baylor University (PhD).
