David HirzelDavid Hirzel is a maritime historian, author and small business owner. His enduring interest in world history and the evolution of societies focuses on the study of polar exploration, and his vocation in architecture expands those interests. David woks out of his design office overlooking the sea in Pacifica, California, with a drafting table, a wide desk and an even wider library of technical and history books to hand. His polar books include a three-part polar biography of the Irish explorer Tom Crean, who was a key player in Captain Scott and Ernest Shackleton's expeditions. David is also a popular lecturer on board polar and maritime exploration cruise ships. Read More Read Less
