Camillo Castiglioni (22 October 1879 – 18 December 1957) was an Italian-Austrian Jewish financier and banker, and was the wealthiest man in Central Europe during World War I. Nicknamed "Austrian Stinnes", he was active in aviation's pioneering days and invested in the arts. Castiglioni was credited as being instrumental to the founding of what would eventually become BMW AG. Early life Castiglioni was born in Trieste, then part of Austria-Hungary, to the chief rabbi. His older brother was Arturo Castiglioni. It is not known when Camillo developed his interest in aviation, but it is known that he was passionate about flying. Camillo's education was primarily law, gaining employment as an attorney and legal officer of a bank in Padua, quickly learning international finance and how to manage capital. He was the son of a rubber maker, so naturally Camillo found work with the Austro-American Gummiwarenfabrik AG (rubber products) in Vienna as an agent for the Kaufmann automobile tire division in Constantinople. Camillo found great success in this position, demonstrating his abilities to negotiate and structure financial deals. In fact, Camillo was so successful, he was promoted to director of the export department of the parent company in Vienna. Around 1901, along with Viktor Silberer and Franz Hinterstoissera Camillo helped to create the Viennese aero club (later Austrian aero club). He eventually was made deputy director, then in 1904 he was appointed to general director of the company. Through his experience in the rubber and tire production field, Camillo saw the birth of aviation as an industry, going from a ballooning hobby, to makeshift glider craft requiring tires, to fully operational aircraft operated by engines. He met many influential men in his business, and came to realize that aviation sparked not only his passion for flight, but also recognized the tremendous financial opportunity of aviation's potential as an industry. In order to draw from the arising enthusiasm for airplanes and ballooning, as well as to take advantage of the lucrative business the hobby generated, Camillo established one of his first companies, Luftfahrzeug-Gesellschaft, in 1907. Being a pure commercial firm – it acquired the Etrich balloon patents and sold balloon fliers in Austria Hungary. There were many contests that these inspired balloon drivers entered, and Camillo was no different- he bought his own balloon and successfully took his balloon driver examination on 24 August 1909.
