Austrian undersea explorer and writer Hans Hass has died aged 94. His expeditions, books and films were part of the pioneering 20th-century efforts to unlock the secrets of the deep. Sharks were his pet project.
Hans Hass’ family announced on Saturday that the famous Austrian zoologist and undersea explorer died last weekend at the age of 94. Hass published 32 books and produced 73 films during his career on the seas in his “Xarifa” boat. He was born in 1919 in Vienna.
