The celebrated architect Stanford White was a louche man-about-town and a canny cultural entrepreneur, the creator of landmarks that raised the stature of the American built environment. Augustus Saint-Gaudens, a sculptor and the son of an immigrant shoemaker, was a moody introvert and a committed procrastinator whose painstaking work brought emotional depth to American statuary. Over years of acquaintance, their relationship evolved into a partnership that defined the art of the Gilded Age.

In Stan and Gus, the acclaimed historian Henry Wiencek tells the story of a fruitful, complicated relationship. After pursuing their own careers in Italy and France, the two men met again back home, where they forged era-defining monuments, including White’s Washington Square Arch and Park Avenue Armory in Manhattan and Saint-Gaudens’s memorials to Colonel Robert Gould Shaw and Clover Adams in Boston and Washington, D.C., respectively. Over the course of decades, White protected Saint-Gaudens from impatient clients when he failed to complete projects on time. Meanwhile, Saint-Gaudens challenged White to take his artistic gifts seriously. But alongside the brilliant commissions were sordid debaucheries—and White’s sensational murder in 1906.
