Attorney, urbanist, and historian Adrian Untermyer aims to lift that veil, and reveal the inner workings of the three branches of government and how they have shaped and affected the preservation movement — its successes and the challenges it still faces — in our city and state. He’s launched a new podcast called “Wrecking Ball” in association with the Historical Society of the New York Courts to do just that, in which he brings in legal and preservation scholars to discuss some of these defining preservation battles, such as those to save Castle Clinton, Penn Station, and Washington Square Park. It’s only appropriate that this conversation, with Village Preservation Exec. Dir. Andrew Berman, take place at Jefferson Market Library — subject of one of the great preservation battles of the 20th century, and itself formerly a New York Courthouse. Come hear more about these battles, about the new podcast illuminating them, and about Adrian’s fascinating ongoing work.
