Joe Bertony

Joseph Bertony (4 March 1922 – 7 April 2019) was a French-born Australian engineer. Trained as a naval architect, he served in the

The forced labourers received very little food, being lucky to receive a loaf of bread per day between five men.[1]^[2] Bertony had a good metabolism and would often give his allocation to other prisoners, angering the SS guards. He was sometimes put to work on farms where he was designated a "carotenfuhrer", a prisoner with responsibility for guarding silos of carrots.^[2] The prisoners were prohibited from eating the crops they harvested, and during this time Bertony survived by eating boiled grass.^[1] As "carotenfuhrer" if Bertony allowed a prisoner to eat the carrots, which he did many times, both he and the prisoner would be stripped and flogged.^[2]

Towards the end of the war, in 1945 with US forces approaching, the prisoners from Buchenwald were marched to the German-Czech border and loaded onto a cattle train. They were then taken to a remote spot to be executed by shooting. Bertony anticipated this and escaped the train in the company of another man.^[2] The two men endured ten days in the snow with no food and clad only in their thin camp uniforms.^[1][2] They survived to be rescued and became firm friends for the rest of their lives.^[2] Bertony was awarded the Croix de Guerre by the French government for his actions during this escape.^[1]

Sydney Opera House

Bertony moved to Australia in 1953 to work at the uranium mines at Rum Jungle, Northern Territory.^[2][1] At the time Australia operated a scheme that allowed European citizens permanent residency if they secured work in the country for two years.^[2] Bertony was given a job at Hornibrook, a construction company famous for its work on bridges, that satisfied this requirement.^[1][2]

During the early 1960s Bertony worked on the construction of the Sydney Opera House.^[2] The building's design with a number of large "sails" made up of 22,194 pre-cast concrete segments proved challenging to construct.^[2][1] The segments were to be fixed in position with epoxy resin and Bertony determined that a temporary steel "erection arch" falsework would be required to support the structure in the temporary condition.^[2] Bertony settled on a mobile telescopic truss system and completed the 30,000 necessary calculations by hand in six months.^[2][3] The structure, which had no flat elements, was complex, and the margin of error required was 0.5 inches (1.3 cm).^[1][2]

The calculations had to be checked for safety, and this was carried out by computer. The only machine in the country powerful enough to do so was the IBM 7090 at the Long Range Weapons Establishment at Woomera.^[3][1] This was only available during night time for one week in every month.^[2] One of Bertony's colleagues, David Evans, operated the computer and reported that no errors were found in Bertony's calculations.^[2][3] Evans later stated that Bertony's work had greatly helped the construction programme and claimed that "it would have taken many minds and many rounds of trial and error, and a much longer time and a much bigger budget, to get those ribs in the air if Joe hadn't been there".^[4] Sydney Opera House chief executive Louise Herron also stated "Bertony was a genius. Without him, the spectacular sails might never have become a reality".^[3]

Later life

After the Opera House, Bertony worked on other projects in Sydney including the

Bertony's wife was a pianist and physiotherapist at Hornibrook.[2]^[1] They had no children and she died in 2016.^[1] Bertony was a lover of French food and dined out regularly in Sydney's restaurants. He also held a keen interest in electric vehicles and helped to mentor young engineers.^[2] Bertony died at his home in Sydney on 7 April 2019.^[3]
