Question: Which of Joseph Reinach's two brothers is the oldest? Passage 1:Consequently, in 1870, it moved to a (then greenfield) site on Gilmorehill in the West End of the city, around three miles (5 km) west of its previous location, enclosed by a large meander of the River Kelvin. The original site on the High Street was sold to the City of Glasgow Union Railway and replaced by the College goods yard. The new-build campus was designed by Sir George Gilbert Scott in the Gothic revival style. The largest of these buildings echoed, on a far grander scale, the original High Street campus's twin-quadrangle layout, and may have been inspired by Ypres' late medieval cloth hall; Gilmorehill in turn inspired the design of the Clocktower complex of buildings for the new University of Otago in New Zealand. In 1879, Gilbert Scott's son, Oldrid, completed this original vision by building an open undercroft forming two quadrangles, above which is his grand Bute Hall (used for examinations and graduation ceremonies), named after its donor, John Crichton-Stuart, 3rd Marquess of Bute. Oldrid also later added a spire to the building's signature gothic bell tower in 1887, bringing it to a total height of some . The local Bishopbriggs blond sandstone cladding and Gothic design of the building's exterior belie the modernity of its Victorian construction; Scott's building is structured upon what was then a cutting-edge riveted iron frame construction, supporting a lightweight wooden-beam roof. The building also forms the second-largest example of Gothic revival architecture in Britain, after the Palace of Westminster. An illustration of the Main Building currently features on the reverse side of the current series of £100 notes issued by the Clydesdale Bank.
 Passage 2: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.
 Passage 3:Gunnarsson was born in Borås, Sweden. Gunnarsson became a lieutenant in 1974 and he attended the Marine Corps Command and Staff College at the Marine Corps Base Quantico from 1991 to 1992.
