857 Fifth Avenue, 1929.

In 1906, after seeing the new mansions of Fifth Avenue rise around him, particularly the new gleaming white Thomas Fortune Ryan mansion next door, George Gould decided to demolish his home and built something new.

He hired Philadelphia architect Horace Trumbauer, who created an Italianate mansion that matched its neighbor's style, down to a rusticated base that was nearly exactly the same. The home once again became the host to a couple society wedding, this time for the daughters of George.

George would die in 1923 and following his death, a major battle ensued over his wealth and real estate between his older children and his second wife (and former mistress with whom he had children while still married to his first wife).

The house was eventually purchased by a Vanderbilt relative. Sold by that owner in 1951 for a mere $400,000 (it was built in 1907 for $1.25 million), it was torn down in the early 1960s and replaced with a 19-story building.
