Harry Macklowe and Linda Macklowe had quietly amassed one of the largest collections of private art the world had ever seen. Harry was a highly-successful real estate developer, but it was his wife, Linda, who had the stronger passion for fine art. On weekends, the couple visited art galleries and shows, developing relationships with gallery owners and world-renowned artists. Over decades of marriage, the couple amassed 165 iconic works by artists like Picasso, Pollock, and Warhol.
