Biography
Biography
In 1991, Proksch was convicted in connection with the sinking of the freighter Lucona, which had been destroyed by a time bomb in the Indian Ocean on 23 January 1977. Six people were killed and six survived. The cargo, declared as valuable uranium-processing equipment and insured for more than 200 million Austrian schillings, was later shown to have consisted largely of scrap metal. The case became one of the largest political scandals in postwar Austria, involving years of obstruction, political intervention and a parliamentary investigation. Proksch was ultimately sentenced to life imprisonment and died in prison in 2001.

Early life and career
Early life and career
Proksch was born in Rostock in 1934 and later moved to Austria. Under the name Serge Kirchhofer, he became successful as a designer, particularly in the field of eyewear. In the 1950s he was hired by the industrialist Wilhelm Anger after a design competition, and later became associated with brands such as Viennaline, Serge Kirchhofer and Carrera. Proksch cultivated a public image as an eccentric, charismatic and provocative member of Viennese society. He founded and participated in several business ventures and operated a well-financed advertising studio in Vienna. His social rise culminated in his acquisition of Demel, the prestigious Viennese confectioner, which became closely associated with his public persona.
Club 45 and political network
Club 45 and political network
At Demel, Proksch hosted the Club 45, a social club associated with leading Social Democratic politicians, business figures and members of Vienna's cultural establishment. The club was modeled partly on English gentlemen's clubs and became a symbol of Proksch's influence within Austria's political and social elite. During the investigation into the Lucona affair, Proksch's political connections became a central issue. A parliamentary committee later examined interventions by members of his circle, especially in relation to delays and obstruction in the criminal investigation. Austrian sources describe the affair as one of the largest political scandals of the Second Republic.
Lucona sinking
Lucona sinking
On 23 January 1977, the freighter Lucona sank in the Indian Ocean after an explosion near the Maldives. Six of the twelve people on board were killed. Proksch, whose company Zapata AG owned the cargo, claimed that the ship had been transporting valuable uranium-processing equipment and filed an insurance claim for approximately 212 million Austrian schillings, roughly US$20 million. Suspicion soon arose that the sinking had not been an accident and that the cargo had been falsely declared. Investigators eventually concluded that the ship had carried scrap metal rather than valuable industrial equipment. According to later accounts, the ship had been deliberately sunk with a time bomb as part of an insurance fraud. The case was delayed for years. Political interventions, conflicting testimony and disputed cargo documents complicated the investigation. The journalist Hans Pretterebner played a major role in keeping the scandal in public view, first through investigative reporting and later through his book Der Fall Lucona, which was published in the late 1980s.
Flight, arrest and trial
Flight, arrest and trial
After publication of Pretterebner's book and increasing legal pressure, Proksch fled to the Philippines. He underwent cosmetic surgery and used false papers while abroad. In 1989, he returned to Europe under a false identity but was recognized and arrested after arriving in Vienna. The trial was one of the most elaborate and expensive in Austrian legal history. A decisive element was the deep-sea search for the wreck of the Lucona. The wreck was located in the Indian Ocean by a team involving shipwreck investigator David Mearns, and the findings supported the conclusion that the ship had been deliberately destroyed by an explosive device. On 11 March 1991, Proksch was convicted of murder and fraud and sentenced to 20 years in prison. The sentence was later increased to life imprisonment. He remained imprisoned at Graz-Karlau Prison until his death.
Political consequences
Political consequences
The Lucona affair caused major political repercussions in Austria. A parliamentary inquiry examined the role of Proksch's political network and the handling of the investigation. The affair contributed to the resignation of senior politicians, including former foreign minister and later National Council president Leopold Gratz and interior minister Karl Blecha. Gratz was later convicted in connection with forged cargo documents and received a fine. Former defence minister Karl Lütgendorf was also drawn into the scandal because of allegations concerning the provision of explosives. He died in 1981; his death was officially treated as suicide, although it remained surrounded by public speculation.
