|Occupation||Underwater diver, Documentary filmmaker|
Hans Hass (23 January 1919 – 16 June 2013 (age 94)) was an Austrian biologist and underwater diving pioneer. He was known mainly for being among the first scientists to popularise coral reefs, stingrays and sharks. He pioneered the making of documentaries filmed underwater. He led development of the aqualung and of a type of rebreather. He is known, too, for his energon theory and his commitment to protecting the environment.
Hass was born in Vienna; his father was an attorney and Hass initially pursued law. However, Hass had a formative encounter with the American diver Guy Gilpatric while on a Riviera holiday in 1938 which included underwater hunting and photography. After making expeditions to the Caribbean Sea 1938-39 and writing his first professional articles, in 1940 Hass switched from reading law to zoology studies and graduated with a Ph.D. from the University of Berlin in 1943 at the Faculty of Biology. His thesis was the first scientific research using an autonomous rebreather diving equipment. In his early diving he used rebreathers, which he had made for him by the German diving gear makers Dräger: he had these sets made with the breathing bag on his back, as he did not like the bag-on-chest "frogman look". Hass and his team of researchers logged over 2000 dives utilising oxygen rebreathers from 1942 to 1953.
Although, in a book by Callum Roberts, Don Stewart, one of the first scuba operators on the Caribbean island of Bonaire, blames Hass for single-handedly hunting the Atlantic goliath grouper to local extinction, the author clearly refutes that claim later in the same paragraph.
Hass published "Diving to Adventure," his first book of underwater photographs, in 1939, and some credit him with developing one of the first underwater cameras. Hass completed his first underwater video called Pirsch unter Wasser (Stalking under Water) in 1940. It was published by the Universum Film AG, lasted originally only 16 minutes and was shown in cinemas before the main film, but would eventually be extended by additional filming done in the Adriatic Sea close to Dubrovnik.
Hass moved from Vienna to Berlin in 1941, where he founded the tax privileged society Expedition für biologische Meereskunde (Expedition for biological oceanography).
On the proceeds of his hundreds of lectures, Hass was able to buy in 1942 the sailing ship Seeteufel. But he was not able to use the ship for his planned expedition because the ship was in the harbour of Stettin and it was not possible to bring it during the war to the Mediterranean Sea.
Hass rented therefore in 1942 a ship in Piraeus and sailed for several months in the Aegean Sea and the Sea of Crete. Before the war this ship had been owned by the University of Vienna. During this expedition he took film and photos underwater. Hass had read the book Raubfischer in Hellas (Rape Fishing in Greece) written in 1939 by Werner Helwig. Hass found this group near Skiathos and was able to film their dynamite fishing under water.
In spring and summer 1943 Hass stayed for several months at the Stazione Zoologica in Naples and Capri to study and collect Bryozoa, aquatic invertebrate animals, for his doctoral thesis in zoology. In February 1944 he completed the thesis, to become a Doctor of Science.
Until the end of the war Hass lived and worked in the film studios of Universum Film AG in Babelsberg near Berlin to cut and finish his film about the expedition in the Aegean Sea. This 84 minute underwater film, Menschen unter Haien (Men among Sharks), was released in 1947. It shows marine life including wrasse, jellyfish, sponges, sea anemones and rays. Highlights are the dynamite fishing and interaction of divers with sharks.
In Babelsberg he met Hannelore Schroth, a famous German actress. Hans and Hannelore married in 1945.
Post war activity and fame
In 1945 the Seeteufel was lost when the Soviets captured Königsberg. In 1947 his film Menschen unter Haien had its world premiere in Zurich, and his most popular book with a very similar title was released in 1948. As a consequence, he got contracts with Herzog-Film (Munich) and Sascha-Film (Vienna). He also went on his first "Xarifa" expeditions. The new research ship, named 'Xarifa', was mostly financed through photo safaris in the Red Sea and by the BBC.
Hass produced 105 commercial films, many featuring himself and his second wife, who was an expert diver. In 1951, Hass's film Under the Red Sea was awarded first prize at the Venice Film Festival.
After expeditions in East Africa and South Asia his first TV series were developed in 1959, in 1961 for the first time about creatures outside the water. This was followed by behavioural research and the 'energon theory' from 1963 to 1966. From his behavioural research, Hass formed his energon hypothesis, the focus of his work in later years. It posits that the behaviours of all life-forms — human, nonhuman animal and plant — have common origins. Combined with management strategies, in 1969 Hass published about commonalities with evolution. In the 1970s he addressed environmental and commercial themes and was appointed to a professorship by the University of Vienna. In 1983 he started long term studies and tutorials about predatory instincts in profession. Hass consolidated marine biology, behaviour research and management theories under one umbrella. From his point of view his energon theory cannot be disproved. In 1989 he addressed himself to environmental themes.
Following the disappearance of the Australian Prime Minister Harold Holt in the waters of Cheviot Beach at Portsea, Victoria on 17 December 1967, Hass visited Australia and explored the area where Holt disappeared for his 1971 film documentary Das Geheimnis der Cheviot Bay (The Secret of Cheviot Bay). In an interview with Harry Martin for the ABC's current affairs programme "A.M" Hass said that having observed the underwater conditions of the area with its sharp and jagged rocks he was convinced that Holt had been trapped in the structure of one of these rocks and his body considerably torn by the nature of the forces of the sea and the sharp rocks.
Hass acknowledged a rivalry with the better-known French scientist Jacques Cousteau; according to the New York Times obituary, Hass told historian Tim Ecott that "For Cousteau there exists only Cousteau. He never acknowledged others or corrected the impression that he wasn't the first in diving or underwater photography."
Hass died on 16 June 2013 in Vienna. He was 94 and was survived by his wife and daughter Meta. Lotte Hass died in January 2015. Hass's son Hans Hass Jr., an actor and composer, committed suicide in 2009.
