Swiss oceanographer Jacques E. Piccard pictured in Palm Beach, Fla., in the late 1960s. Piccard, who died in 2008, was posthumously awarded the Hubbard Medal, the National Geographic highest honor, at a ceremony in Washington, D.C., on June 14, 2012, for his record-breaking dive to the ocean's deepest point with Don Walsh on Jan. 23, 1960. Aboard the bathyscaphe Trieste, Piccard and Walsh were the first to reach the bottom of the Pacific Ocean's Mariana Trench. (Photo by Otis Imboden/National Geographic; ? National Geographic)
