The John Walker House contributes significantly to the cultural heritage and visual beauty of the District of Columbia. The house has long been known as the Gannt-Williams House and its date of construction initially thought to be circa 1805, but research in the Georgetown deed and assessment records shows that the house was not built until 1816-1817, when it was the property of Isaac Owens. The house represents a typical Federal-style townhouse found in Georgetown in the early nineteenth century.
In the twentieth century, the Walker House has been the home of Washington newspaper columnist Drew Pearson and John Walker, former director of the National Gallery of Art.
