Benjamin Baillauddouard Benjamin Baillaud (February 14, 1848 – July 8, 1934) was a French astronomer. Baillard studied at the cole Normale Suprieure and the University of Paris. He worked as an assistant at the Paris Observatory beginning in 1872. Later he was director of the Toulouse Observatory from 1878 to 1907, during much of this time serving as Dean of Toulouse University Faculty of Science. He greatly expanded the observatory and enthusiastically supported the Carte du Ciel project. He specialized in celestial mechanics, in particular the motions of the satellites of Saturn. In 1903, the observatory took over a facility on the Pic du Midi in the Pyrenees that had been founded by amateurs in the 1850s with the goal of putting a telescope there. However, the height of 2865 metres (9400 feet) posed formidable logistical challenges and the ambition had remained unrealised though a meteorological observatory had operated from 1873 to 1880. Baillaud organised a team of soldiers to erect a 0.5 metre (20 inch) reflecting telescope, and 0.25 metre refracting telescope on the summit. In 1907, he became director of the Paris Observatory where he immediately set to work to relaunch the stalled Carte du Ciel project with a conference held at the observatory, entertained by singers from the Paris Opera and refreshed by wine provided by the director of the Bordeaux Observatory. Though the French government agreed to fund the project, it was becoming increasingly clear that its objectives were hopelessly unrealistic. Baillard was active in time standardisation, becoming the founding president of the International Time Bureau and initiating the transmission of a time signal from the Eiffel Tower. Baillard maintained the observatory and the time signal throughout World War I, even though the German howitzer Big Bertha was targeted on the nominal co-ordinates of Paris, the location of the observatory! Baillard's concern for the astronomical time standard led him to be an outspoken opponent of daylight saving time. Baillaud became founding president of the International Astronomical Union in 1919. He retired as director of the Paris Observatory in 1926. He won the Bruce Medal in 1923. A crater on the Moon is named after him. Note however asteroid 1280 Baillauda is named after his son Jules Baillaud rather than for him. External links Obituaries Baillaud, Benjamin Baillaud, Benjamin
