The Man Who Made the Citroën Car and Helped Win World War I

As a child, André Citroën was inspired by the Eiffel Tower. He lived to see his name displayed on it. This early “billboard” marketing technique is still a Guinness World Record for largest advertising sign.
André-Gustave Citroën (1878-1935) was born in Paris to a Dutch-Jewish father and Polish-Jewish mother. The last name “Citroën” comes from his grandfather, who sold fruit for a living in the Netherlands and was known as Limoenman, so his son made the family last name Citroen, which means “lemon”. As a child, Citroën was inspired by the Eiffel Tower and by the works of Jules Verne and dreamed of becoming an engineer. After graduating with an engineering degree, Citroën went on a trip to Poland to see his mother’s birthplace. There, he saw a carpenter working with a gear that had a “fish bone” structure. Citroën realized that such gears could be used in automobiles to make them quieter and more efficient. He bought the patent from the carpenter, then tweaked the designs until he came up with the automotive double helical gear. The Mors auto company successfully integrated these gears to make better cars, and by 1906 Citroën was the company’s director. With the outbreak of World War I, factories were being converted to produce weapons, and Citroën soon became world-renowned for increasing factory productivity. He took charge of fellow car-maker Renault’s large plant, now having its 35,000 employees making armaments. Citroën’s work played a key role in ensuring the Allies were well-armed and helping them win the war. Following the war, Citroën founded his own Citroën automobile company in 1919. Within just a dozen years, it became the world’s fourth largest car manufacturer. The company was most famous for its executive Traction Avant model, which pioneered a number of revolutionary features including independent suspensions on all four wheels and front-wheel drive. Investing so much money into research and development ultimately drove the company to bankruptcy and it was bought out by its tire maker Michelin. Citroën died the following year from cancer. He was buried in Paris’ famous Montparnasse Cemetery, with a traditional Jewish ceremony presided by Paris’ chief rabbi. A number of streets and parks in the city are named after him, and in 1998 Citroën was inducted into the Automotive Hall of Fame. Meanwhile, his company retained his original vision, and continued to pioneer many new technologies (like modern disc brakes, self-leveling suspensions, and swiveling headlights), becoming one of the most iconic car brands in the world.

Yuri Bentsionovich Milner (b. 1961) was born in Moscow. He studied theoretical physics at Moscow State University before working at the prestigious Lebedev Physical Institute. He found that his abilities in physics were not the best (especially because he was placed on a lower track due to his being Jewish), and decided to switch to business. He first tried selling computers, then went to do an MBA at the University of Pennsylvania, becoming the first person from the Soviet Union to officially study in the US. Upon graduation, he got a job at the World Bank, and in 1995 was made CEO of Russian oligarch Mikhail Khodorkovsky’s investment company. In 1999, Milner read an article and decided it was a good idea to start an online business. He began a series of ventures that brought American-style sites to Russia, including Molotok.ru (the Russian eBay), Boom.ru (free webhosting), and 24×7 (Russia’s Amazon). In 2005, Milner established his own investment fund, Digital Sky Technologies. Five years later, his Mail.ru went public on the London Stock Exchange with a valuation of $5.6 billion. That same year, Milner bought pioneering Israeli instant messaging company ICQ, and has since invested an additional $150 million in Israeli startups. Milner’s venture capital fund has become one of the world’s greatest. He was among the first to invest in Facebook, with an initial $200 million, and plenty more since. He also invested $800 million in Twitter, $125 million in WhatsApp, and $1.6 billion in Alibaba, in addition to Groupon, Snapchat, Airbnb, and Spotify. In 2012, Milner established the Breakthrough Prize, awarding $3 million to great achievements in Physics, Life Sciences, and Mathematics. This is now the largest scientific award in the world, trumping even the Nobel Prize. In 2015, Milner founded the Breakthrough Initiatives to investigate life on other planets. Its first project is a $100 million, 10-year endeavour called “Listen”, searching for radio and laser signals from distant stars with the most sensitive equipment in the world. The most recent Breakthrough Initiative is “Starshot”, investing $100 million to develop a spacecraft that will be accelerated to 20% of the speed of light and take a 20 year journey to our nearest star. Milner also awards (together with
