Man who sank Lusitania was invited here in 1966

Attendees will include relatives of those who drowned, ambassadors, senior representatives of Cunard, and representatives of the State and the naval service. One victim, Alfred Gwynne Vanderbilt, who was the richest man in America in 1915, will be represented by his grandson and namesake, who described the torpedoing, of what was once the world’s largest passenger ship, as ‘an act of international terrorism’.
This sinking of RMS Lusitania is said to have prompted the entry of the United States into World War I, and this resulted in a quarter of a million US casualties, including over 58,000 American deaths.
