Typewriters that belonged to notable 20th century people are on display in a Northeastern University gallery.

Machines once owned by Tennessee Williams, Ernest Hemingway, John Lennon, Jack Kevorkian and "Unabomber" Theodore Kaczynski are among those on exhibit.

The collection is owned by Steve Soboroff, a California businessman whose daughter is a Northeastern graduate.

It includes writings that former owners typed on the machines, including an excerpt from Williams' play "The Glass Menagerie."

The exhibit will be open until September 25th.
