S.I. Newhouse Jr., Who Turned Condé Nast Into a Magazine Powerhouse, Dies at 89br “No one will ever thank you for saving money at Condé Nast magazines,” Mr. Libermanbr told one of his editors, according to a 1996 Wall Street Journal article.br “With Si’s passing, the big chapters in the history of magazines — as written by men like Si and Henry Luce — will have come to an end,” said Mr. Carter, who announced last monthbr that he would leave Vanity Fair in December after 25 years.br Though he was a shy man and often painfully awkward in public, Mr. Newhouse hired some of the most charismatic magazine editors of the late 20th century, among them Tina Brownbr and Graydon Carter at Vanity Fair and Diana Vreeland and Anna Wintour at Vogue, and encouraged them to behave like the celebrities they extolled in his publications.
