William Cohen
On the afternoon of June 10, 2009, Cohen was present at the United States Holocaust Museum, waiting for his wife Janet Langhart, for the world premiere of her one-act play, Anne and Emmett.  The play imagines a conversation between Anne Frank and Emmett Till. While Cohen waited, an elderly man with a long gun attacked the facility, fatally shooting a security guard before being wounded himself by the other guards. Cohen and his wife were not injured during the attack.
