On this date in 1850, Sofia Kovalevskaya was born in Moscow, Russian Empire. Despite her early aptitude with mathematics, women were not allowed to attend university in Russia, so she arranged a fictitious marriage to Vladimir Kovalevskij and emigrated to Germany. In 1874 she became the first woman in Europe to earn a doctoral degree in mathematics. One of the papers she published at the time introduced a theorem that gave the conditions for solutions to a set of partial differential equations. In the 1880s she moved to Sweden and became the first woman to hold a professorial chair in northern Europe and one of the first women to work for a scientific journal as an editor.
