December 9, 2012, marks what would have been the 100th birthday of former U.S. House Speaker and Massachusetts Democrat Thomas “Tip” O’Neill. In this event hosted by the Cambridge Public Library, a panel including three of "Tip" O’Neill’s children look back at his life and career. MSNBC “Hardball” host Chris Matthews - who served as a press aide to Speaker O’Neill in the 1980s - moderates the conversation. “Tip” O’Neill served in the U.S. House from 1953-87 and was House Speaker from 1977-87. He died in 1994 at the age of 81.
