Harry Macklowe’s divorce is quickly turning into an even bigger family feud. In new court filings, Macklowe, 79, accuses his son, Billy Macklowe, 48, of breaching his fiduciary duties and of “essentially” shutting down his business operations, Page Six reported. The elder Macklowe filed for divorce from his wife, Linda, in May, leaving her for Patricia Landeau, president of French Friends of the Israel Museum.
