The Medford Historical Society & Museum welcomes author and historian Anthony Sammarco for a talk on his recent book Jordan Marsh: The World’s Largest Department Store. The book tells the story of the store that opened in 1851, before the Civil War, and eventually made its home on the corner of Washington Street in Boston’s Downtown Crossing. Always a destination for shoppers who went into town, the five-story building, designed by Winslow & Wethell, was the first of a new concept, the department store, with its many departments under one roof.  Come and enjoy this history adventure as only Mr. Sammarco presents it.
