Scope and content:

Primarily the family properties of 1009 Fifth Avenue in New York City; Four Acres, Les Terrasses, and Pinecrest in Durham; Linden Court in Irvington, NY; and Sarmiento in Palm Beach.

Biographical / historical:

1009 Fifth Avenue was built around 1900 and first owned by Benjamin N. Duke. It stayed in the family after his death until it was sold in 2006, although it had been occupied by different tenants before then.

Four Acres was Benjamin N. and Sarah P. Duke's last home in Durham. It was given to Duke University upon his death, who later sold it to North Carolina Mutual Life Insurance Company in 1960. After demolition, they built their new headquarters upon on the land.

Les Terrasses was MDBTS' primary residence from 1946/1947 until her death. After sitting vacant, it was sold in 2021 then burned by the local fire department for training purposes in 2023.

Linden Court was bought by Mary Duke Biddle in 1921 and sold after her death. It was briefly used by Mali for diplomatic purposes before reentering private ownership and becoming a conference center.

Pinecrest was bought by Mary Duke Biddle in 1935 and stayed in the family after her death. It was eventually sold in 2021 and the land developed into a community bearing the same name (the two main original homes still stand).

Sarmiento was built in 1923 and first owned by the Biddles before their divorce and being sold by 1936.
