Nathan Green Caldwell (July 16, 1912 – February 11, 1985) was an American journalist who spent fifty years on the staff of the Nashville Tennessean. He was a co-winner of the Pulitzer Prize for National Reporting in 1962. Early life and education Born in St. Charles, Missouri, Caldwell was the son of Albert Green Caldwell, a mechanical engineer, and Sara (Jetton) Caldwell, both Tennessee natives. One of his grandfathers (apparently Wailer C. Caldwell) was a Tennessee Supreme Court justice. He grew up in Lakeland, Florida. After his father died, Caldwell, at the age of ten, went to work on the Lakeland Evening Ledger as a solicitor of circulation. While still a child and in his early teens, according to a 1979 interview, he sold "hair straighteners, a line of cosmetics to blacks, delivered newspapers and sold newspapers as a street salesman." In addition, he worked nights as a masseur. At about age 14 he formed a small "citrus fruit tree trimming, spraying, fertilizing service" that employed "about eighteen kids."

His mother managed to arrange "a grant or scholarship or something as a potential ministerial student" so he could start as a freshman at Southwestern at Memphis. His freshman English teacher was Robert Penn Warren. While studying there, he worked in circulation on the Memphis Press-Scimitar and Memphis Commercial Appeal. In 1931, after a year at Southwestern, he went to Trenton, Tennessee, where he worked on the Trenton Herald Democrat. He then attended Cumberland University Law School in Lebanon, Tennessee, where two of his great grandfathers "had been very successful lawyers and politicians and law teachers." One of them was Nathan Green Sr., who was a founder of the law school. Green's son, Caldwell's maternal grandfather, was Nathan Green Jr., a law professor there.
