Originally from Richmond, Virginia, David Perry was raised on the book Oliver Hazard Perry: Boy of the Sea about his ancestor (according to family lore) the legendary naval hero of 1812. He always knew that one day he would trod the deck of a ship.

Born in Caracas, Venezuela to a Spanish family, Alfredo Casuso first returned to his ancestral land as a child aboard the S.S. Begoña. In later years, he would discover a rich family history including the story of his grandfather's emigration aboard the classic Marques de Comillas.

David served as a junior officer aboard Crystal Symphony, editing the daily newspaper for which he wrote the first-ever regularly-published onboard column about maritime history, Liner Lore. During this time he circumnavigated the globe two-and-half times and visited 45 countries.

Since 1999, Alfredo and David have become regulars at sea: David talking about ships and Alfredo providing design and technical expertise.

David & Alfredo's Linerlore lectures on maritime history have been consistently rated one of the most popular passenger presentations aboard whatever ship upon which they are lucky enough to be sailing. On dry land, they make their home in San Francisco, California.
