Charleston Museum is the oldest museum in the United States, having been founded in 1773. An Egyptian mummy and other antiquities were acquired in the nineteenth century, but the archaeology collections expanded under the influence of Laura Bragg (1881–1978) from 1909 onwards. Bragg eventurally became the Director of the museum in 1920, the first US woman to lead a museum institution.
Museum archives show that Laura Bragg was in personal correspondence with Flinders Petrie, leading to material being sent over. At least 50 objects can be linked to Flinders Petrie, including Predynastic pottery, early dynastic copper and stone vessels [with thanks to Jennifer McCormick and Martha Zierden for the information].
