Update: Paul Allen passed away on October 15, 2018. The Microsoft co-founder and son of a World War II veteran, Allen supported a research team that spent years searching for shipwrecks associated with the war. His discoveries also include the U.S.S. Lexington and the world’s largest sunken battleship, the Musashi. David Mearns, a marine scientist who worked with Allen, shared the following today in an email to National Geographic: “Paul’s interest in marine exploration and shipwrecks was very personal, which grew in part from his father’s service during WWII. But in pursuing his passion and curiosity he also invited the world to join these exciting explorations through the computers he helped create. His important discoveries and illumination of naval history have ensured that the sacrifice of those who served is not forgotten.”
