You just might find a document that saves the museum.
This is indeed what happened to Emilie Gruchow, who interned at the Morris-Jumel Mansion in Manhattan during the summer of 2013.
Rebecca Rego Barry tells her story at Smithsonian.com:
Emilie Gruchow, then an archives intern at the Morris-Jumel Mansion in the Washington Heights section of Manhattan, had recently begun working in the historic house’s third-floor attic. When she recalled the day, she was clear that there wasn’t any air-conditioning up there, and the room temperature was averaging about 95 degrees. Her project was to re-catalog the 17th- and 18th-century manuscripts stored in the flat file cabinets. She knew that many of them were historically noteworthy and many required immediate preservation treatment (archival storage in a hot, humid attic is definitely recommended).
