The most well-known developer in New York today may be a man with national aspirations and a propensity to talk off the top of his extravagantly coifed head, but a century ago, the headlines were commanded by a real estate family with an aversion to publicity and the trappings of wealth.

In the early 20th century, the Wendels were perhaps the most powerful landlords in New York City, a dynasty with more than 150 properties in Manhattan worth over $1 billion in today’s dollars. The Wendels were the delight of the local papers, for, rich as they were, the family — six sisters and a brother, all unmarried — lived together in a shuttered mansion without electricity on the northwest corner of Fifth Avenue and 39th Street, and dressed in grim Victorian garb that had gone out of style half a century earlier. Tour buses regularly pulled up in front of “the House of Mystery.”

Douglas Durst may be one of the very few New Yorkers who remembers the Wendel name.
