Attendees will learn and explore Long Island’s history firsthand during “The Gilded Age: A Tour of Gertrude Vanderbilt Whitney’s Long Island Studio” on Nov. 20 at 3 p.m.

The Roslyn Landmark Society and Trinity Episcopal Church are hosting the free event at Roslyn’s Trinity Episcopal Church. Stanford White, a renowned Gilded Age architect, built the church in 1906.

Attendees will learn about Whitney, a sculptor, art collector. There will also be a virtual tour of her studio in Old Westbury.

Whitney was born into the wealthy Vanderbilt family and married into the Whitney family. She also established the Whitney Museum of American Art in New York City in 1931.

“The attendees can really look forward to a fun and vibrant lecture,” Jennifer Lister, executive director of the Roslyn Landmark Society said, “to just learn more about Long Island, its history and the Gilded Age.”

Whitney’s great-grandson, John LeBoutillier, a lifelong Old Westbury resident, will lead the tour. When he was elected to represent New York’s 6th Congressional District in 1980, he was the youngest member of the 97th Congress.

LeBoutillier was also a member of the House Foreign Affairs Committee and Special House POW/MIA Task Force during his tenure. There, he advocated for a continuing investigation into the fate of the 2,500 Americans missing in Indochina in the Vietnam war.

“[LeBoutillier] is a very lively speaker,” said Lister. “He’s very knowledgeable of Long Island and has a great family history.”

LeBoutillier based his book “Harvard Hates America” on his college experience as a 1976 magna cum laude graduate of Harvard College. He has since published articles in The New York Times, The Wall Street Journal, The New York Times Sunday Magazine and other publications.
