in 1978, baron married judy bernard in a jewish ceremony at the harmonie club. in 2007, he paid $103 million for a house in east hampton, new york—the most ever paid for a residential property at that time—from adelaide de menil, heiress to the schlumberger fortune. de menil's house had been built by piecing together historic east hampton buildings that she moved to the property to protect them from demolition. prior to the close of the sale, de menil broke up the structures and moved them to various locations in the town for protection, including six that were moved a mile north to where they will form the new campus of the east hampton town government. baron is now completing a new house, designed by hart howerton, a new york architectural firm with several other projects in the hamptons, which specializes in large-scale land use. the house was included in a 2008 vanity fair article.
