Thomas Edison resided at Glenmont, his 29 room Victorian mansion, for over half of his lifetime. Its architect, Henry Hudson Holly, is considered to be the father of the Queen-Anne style architectural movement in the United States. Holly's crowning achievement, Glenmont, was part of a working estate which presently contains six outbuildings, including a barn and a greenhouse. Examples of Thomas Edison's poured concrete structures, the auto garage and the potting shed, are also still in existence.
The interior of the fully furnished Victorian home is a rare example of Pottier & Stymus interiors, a New York decorating firm that lost the majority of its records in a catastrophic warehouse fire in the year 1888. Glenmont's interiors display rare examples of the firm's modern Gothic style furniture suites and also include decorative arts objects chosen by the company to outfit this home in in Victorian style. The Edison family appreciated the original interiors, consequently making only minimal changes to the home's decoration during their residency.
