The Philadelphia Museum — or Peale’s Museum as it was colloquially known — was born out of the home of Charles Willson Peale (living at 3rd and Lombard Streets) in 1786. Running out of space, he moved the growing collection of natural history specimens and art to the American Philosophical Society (1794 - 1802) and then to the Pennsylvania State House, Independence Hall (1802 - 1827).
This diagram of the second floor of the State House locates the collections as they were displayed from roughly 1821 to 1826. It is based on the work of Peale’s grandson, George Escol Sellers (1808—99), recalled and drawn in his later years.
