The surnames of Alexander, Miller, Hodge, and Warfield are familiar as faculty of Princeton Theological Seminary, but despite his having served over twenty years in the seminary, McGill’s name is not commonly mentioned. This brief biography of Dr. McGill will be the first in a regular series on lesser-known Presbyterian and Reformed ministers, academics, and missionaries of the past. The purpose of the series is two fold, first, simply to inform readers of Reformed Forum about these forgotten personalities, and second, to encourage seminarians and other students to pursue research and writing about these lesser-known figures. In the case of Princeton Seminary, the quartet of surnames mentioned is certainly worth extensive study, but it makes sense that studies of them would be enhanced through excavating the lives of their lesser-known colleagues and friends.
