Charles Warren, a graduate of the Trinity College in Durham, North Carolina, arrived in Chatham, Virginia in 1906.
Warren was hired as headmaster of the Chatham Training School for the 1909-1910 year.
He and John K. Hutton constituted the entire CTS faculty, presiding over seventeen boarding and eighteen day students.
Charles R. Warren was the first to make a significant effort towards addressing the then-dire need for schools in and around Chatham, Virginia.
Warren's most lasting legacy is the ultimate survival of the Chatham Training School, now known as Hargrave Military Academy, to the present day.
