...[NR Editor] John [O'Sullivan's]'s other senior editor, Peter Brimelow, played an important role. Born in England, Brimelow had worked for an array of magazines and newspapers in Canada and the United States. When John brought him in, he already had a day job writing for Forbes. Peter was strikingly handsome, with light-brown hair and piercing blue eyes. He was also one of the most polite journalists I have ever met (the profession pulls for bonhomie, not civility). He had attractive graces and countenance bright. His manner was at odds with his temperament (saturnine, hopeless) and his polemical style (unrelenting).
"Saturnine" apparently means
a. Melancholy or sullen. b. Having or marked by a tendency to be bitter or sardonic
