"My life as a photojournalist has been thrilling, both physically and intellectually," says Roger Ressmeyer. "I've hung from helicopters over molten lava, documented the inner workings of the nuclear industry, and confronted some of the most powerful forces of nature." He also appreciated the extraordinary personal encounters he has had during his career. "I've been so fortunate," Roger says. "I've had one-on-one meetings with some of the greatest scientists, artists, philosophers and leaders of our times." In this gallery, we feature a few highlights from Ressmeyer's career. © ROGER RESSMEYER / Corbis
