“A. Alfred Taubman, ignoring all of his instincts, stayed silent during the price-fixing trial that would end with a prison sentence for the former owner of Sotheby’s auction house. It was a decision that the luxury-mall developer and philanthropist sees as a critical mistake as he reflects on a career in retailing that began as a discount-store salesman and eventually put him at the centre of an art-world scandal… In a memoir being published today, Taubman takes aim at the former executives” at both Sotheby’s and Christie’s auction houses.
