I have tried reading biographies of Charles Hodge the Princeton professor of systematics before but not finished. The bitesize one by S Donald Fortson III is a great overview.
1. His grandfather and great aunt would have heard and appreciated Whitefield
2. Benjamin Franklin was his wife's great grandfather
3. George Muller taught him German
4. He heard Charles Simeon preach in Cambridge
5. He heard Schleiermacher (who he disagreed with but thought was a Christian) preach
6. He became a lifelong friend off Tholuck in Germany
7. On his return from Europe he developed a leg problem that left him lame. When he could walk again he had to use a cane.
8. His study door was always open to his children (and grandchildren)
9. His sons A A Hodge and C W Hodge also taught at Princeton
10. His first book was on Romans and came out in 1835 (the same year as Albert Barnes' work)
