Oil heiress Caroline Wiess Law has left Houston’s Museum of Fine Arts the bulk of her estate. “When all of Law’s assets are sold and the legal proceedings conclude, possibly by the end of this year, the museum could net between $400 million and $450 million. In recent history, this would be one of the biggest, if not the biggest cash gifts to an art museum. This money will help make Houston one of the most important museums in terms of programming and serving the public.”
