The Medford Historical Society & Museum’s annual holiday party will feature a talk by guest speaker Andrew McClellan, a professor of Art History at Tufts University. Professor McClellan will share the fascinating story from his book “Jumbo: Marvel, Myth, & Mascot” (2014), on how the carcass of Jumbo the Elephant was a gift to Tufts College in 1889 from founding trustee and benefactor P.T. Barnum and became the most famous college mascot in the United States. Followed by holiday refreshments, and a chance to meet new and greet old friends.
