The author is the founder and editor of The Unz Review, a leading conservative American political website. He is also a silicon valley entrepreneur, and a one-time candidate for the governor of California. He was once described as 'the smartest guy in his class' at Harvard (class of 1983). His biography on Wikipedia is interesting.
He is Jewish, raised in a Yiddish speaking household, and writes frequently on the Jewish Question.
Back in 1999 I was invited to join Steve Sailer’s HBD email group, where I encountered all sorts of interesting people. The participants were mostly intellectuals or journalists having sharply heterodox views about racial differences, especially those involving IQ and crime, and this was reflected in the somewhat euphemistic title, which stood for “Human Bio-Diversity.” A reasonable sense of the controversial roster is that less than a year earlier a founding member named Glayde Whitney had contributed the Foreword to David Duke’s 700 page opus My Awakening.
