A Legacy of Ownership and Architecture
Early Origins and the Olden Era
The land upon which the estate sits was originally owned by William Penn, the Quaker proprietor of the Province of Pennsylvania. In 1696, William Olden purchased the property and constructed a small white homestead known as the Olden House.
In 1835, Charles Smith Olden, who had amassed wealth through mercantile firms in Philadelphia and New Orleans, began construction of the main mansion. The name "Drumthwacket" is believed to be inspired by Sir Walter Scott's 1819 novel A Legend of Montrose, though modern linguistic sources suggest it derives from Scottish Gaelic words meaning "wooded hill." The original structure featured a center hall with two rooms on each side, a 2.5-story center section, and a prominent portico supported by six Ionic columns.
The Pyne and Spanel Expansions
In 1893, the estate was purchased by Moses Taylor Pyne, a financier and benefactor of Princeton University. Pyne transformed the home into a magnificent estate by adding two wings in 1893 and 1900, designed by architect Raleigh C. Gildersleeve. These additions included a paneled library and extensive grounds featuring greenhouses, bridle paths, a dairy farm, and formal Italian gardens.
The property later passed to Abram Nathaniel Spanel in 1941. An industrialist and inventor who founded the International Latex Corporation (later International Playtex Corporation), Spanel used the mansion's Music Room as a space to conceive many of his patented inventions.

Transition to the Governor's Residence
The state of New Jersey purchased the estate from the Spanels in 1966 to replace Morven as the official governor's mansion. However, it was not until 1982 that it was formally designated as such, following fundraising efforts by the New Jersey Historical Society.
First Lady Deborah Kean established the Drumthwacket Foundation, a non-profit dedicated to the preservation and curation of the house. She oversaw the conversion of the mansion into an executive residence, replacing outdated furnishings with high-quality antiques suitable for ceremonial functions.
Later, First Lady Lucinda Florio (1990–1994) led further critical renovations. Her work focused on the private living quarters, updating antiquated heating, plumbing, and drinking water systems, and adding essential storage spaces and window treatments. She also restored the 11-acre Italianate gardens, which had fallen into disrepair.
