Input: Question: Which of Joseph Reinach's two brothers is the oldest? Passage:He was born in Paris. His two brothers Salomon Reinach and Théodore Reinach would later be known in the field of archaeology. After studying at Lycée Condorcet, he was called to the bar in 1887. He attracted the attention of Léon Gambetta by writing articles on Balkan politics for the Revue bleue, and joined the staff of the Republique française. In Gambetta's grand ministère, Reinach was his secretary and tried to obtain a partial revision of the constitution and list proportional representation. In the République française he waged a steady war against General Boulanger, which resulted in three duels, one with Edmond Magnier and two with Paul Déroulède. Between 1889 and 1898, he sat for the Chamber of Deputies for Digne.
