The whole world is convinced, that Hans Hass took the first underwater photographs and the first dives without a squander, but this is not the case. In 1937 small group of Slovene natural science students who called themselves Racani, dived beneath the sea without a helmet. They replaced it with an ingenious home-made diving gear. They took their first underwater photographs with their simple home-made "bell".
With this, Slovenes equalled the achievements of the Germans and became the first underwater photographers.
