Baptist Theologian Augustus H. Strong, President of Rochester Theological Seminary from 1872–1912 wrote his "Systematic Theology" during his tenure there. (1886, Rochester, New York: E.R. Andrews.)
Dr. Strong received his B.A. from Yale, his B.Div. from Rochester and his Doctorate from the University of Erlangen, Germany.
Strong's was the primary textbook at the seminary I initially attended and was the primary textbook at the seminary I taught at.
There are a few things to be aware of (as with all such books) such as his ethical monism, his leaning toward theistic evolution, and a form of inclusivism he seems to have accepted. But all in all the rest is the very best of the very best.
