William Buell Sprague was a prolific author and editor, and his two-volume collection of biographies of Presbyterian ministers from the earliest days of American Presbyterianism to 1855 is pure gold. He not only gives you the historical data, but he includes reminisces from friends who knew the subject of each biography. Fascinating, informative, and encouarging. (Sprague also wrote a two-volume set on Congregational ministers - we’ll be uploading those at some point as well).
