Holger Jannasch

Science is an Adventure

Born in Holzminden, Germany, on May 23, 1927, Holger Jannasch pioneered the field of deep-sea microbiology. Inspired by the condition of the food in the infamous Alvin lunch box (1969), Jannasch and his WHOI colleagues conducted the first experiments on microbial decomposition in the deep sea. He would design sophisticated instruments for collecting and culturing bacteria from the ocean floor. After the discovery of deep-ocean hydrothermal vents in the late 1970s, Jannasch confirmed his early theory of the existence of deep-sea bacterial organisms. As he once said: "Science is an adventure, not a career." Jannasch passed away in 1998, but his work lives on at WHOI.
