Alfred Dreyfus ( , also , ; 9 October 1859 – 12 July 1935) was a French artillery officer of Jewish ancestry from Alsace whose trial and conviction in 1894 on charges of treason became one of the most polarizing political dramas in modern French history. The incident has gone down in history as the Dreyfus affair, the reverberations from which were felt throughout Europe. It ultimately ended with Dreyfus's complete exoneration. Early life, family and education Born in Mulhouse, Alsace in 1859, Dreyfus was the youngest of nine children born to Raphaël and Jeannette Dreyfus (née Libmann). Raphaël Dreyfus was a prosperous, self-made Jewish textile manufacturer who had started as a peddler. Alfred was 10 years old when the Franco-Prussian War broke out in the summer of 1870, and following the annexation of Alsace-Lorraine by Germany after the war, he and his family moved to Basel, Switzerland, where he attended high school. The family later relocated to Paris. Early career The childhood experience of seeing his family uprooted by the war with Germany prompted Dreyfus to decide on a career in the military. Following his 18th birthday in October 1877, he enrolled in the elite École Polytechnique military school in Paris, where he received military training and an education in the sciences.

On 18 April 1891, the 31-year-old Dreyfus married 20-year-old Lucie Eugénie Hadamard (1870–1945). They had two children, Pierre (1891–1946) and Jeanne (1893–1981). Three days after the wedding, Dreyfus learned that he had been admitted to the École Supérieure de Guerre or War College. Two years later, he graduated ninth in his class with honorable mention and was immediately designated as a trainee in the French Army's General Staff headquarters, where he would be the only Jewish officer. His father Raphaël died on 13 December 1893. At the War College examination in 1892, his
