The Palmer Mansion was a large private home constructed 1882–1885 at 1350 N. Lake Shore Drive, Chicago, Illinois.

With these great investments in land, she parleyed the fortune into almost double what she had been left and, in 1918, bequeathed an estate of $15,000,000 to her sons Honoré and Potter Palmer Jr.

They sold the Chicago mansion in July 1928, for $3,000,000,[9] to the industrialist Vincent Hugo Bendix, who had invented an automobile starter.

Vincent Bendix contemplated razing the mansion to construct a fifty-story hotel on the site, at an estimated cost of $25,000,000.

[3] The mansion's painting gallery, including works by French painters Claude Monet, Pierre-Auguste Renoir, and Edgar Degas that were collected by Bertha Palmer, was transferred to the Art Institute of Chicago,[10] and the furniture was sold.

[1] The Palmer Mansion was designed by architects Henry Ives Cobb and Charles Sumner Frost, with the lavish interiors executed under the supervision of Joseph Lyman Silsbee.

The mansion's exterior included many turrets and minarets, and on the interior, a spiral staircase without a center support,[7] rising 80 feet (24.4 m) into the central tower.
