a right-wing journalist, , who was trying to assassinate him. Grégori was acquitted by the Parisian court which accepted his defense that he had not meant to kill Dreyfus, meaning merely to graze him. In 1937 Dreyfus's son Pierre published his father's memoirs based on his correspondence between 1899 and 1906. The memoirs were titled Souvenirs et Correspondance and translated into English by Betty Morgan. Dreyfus started corresponding with the marquise Marie-Louise Arconati-Visconti in 1899 and began attending her Thursday (political) salons after his release. They continued their correspondence until her death in 1923. Modern aftermath In October 2021 French president Emmanuel Macron opened a museum dedicated to the Dreyfus affair in Médan in the northwestern suburbs of Paris. He said that nothing could repair the humiliations and injustices Dreyfus had suffered, and "let us not aggravate it by forgetting, deepening or repeating them". The reference to not repeating them follows attempts by the French far right to question Dreyfus's innocence. An army colonel was cashiered in 1994 for publishing an article suggesting that Dreyfus was guilty; far-right politician Jean-Marie Le Pen's lawyer responded that Dreyfus's exoneration was "contrary to all known jurisprudence". Éric Zemmour, a far-right political opponent of Macron, said repeatedly in 2021 that the truth about Dreyfus was not clear; his innocence was "not obvious". Later life World War I Dreyfus's prison sentence on Devil's Island had taken its toll on his health. He was granted retirement from the army in October 1907 at the age of 48. As a reserve officer, he re-entered the army as a major of artillery at the outbreak of World War I. Serving throughout the war, Dreyfus was promoted to the rank of lieutenant colonel. By then in his mid-50s, Dreyfus served mostly behind the lines of the Western Front, in part as commander of an artillery supply column. However, he also performed front-line duties in 1917, notably at Verdun and on the Chemin des Dames. He was promoted to Officer of the Legion of Honour in November 1918. Dreyfus's son Pierre also served throughout the entire war as an artillery officer, receiving the Croix de guerre. Death Dreyfus died in Paris aged 75, on 12 July 1935, exactly 29 years after his exoneration. Two days later, his funeral cortège passed the Place de la Concorde through the ranks of troops assembled for the Bastille Day national holiday (14 July 1935).
