Biography
Deslandres' undergraduate years at the
In 1868,
In 1898, he joined Janssen at Meudon, increasing the scientific staff by 100%. On Janssen's death in 1907, Deslandres became director and embarked on a programme of expansion. Deslandres was the President of the Société Astronomique de France (SAF), the French astronomical society, from 1907-1909.[2] At the outbreak of World War I in 1914, though already in his 60s, he returned to active service in the engineers as a major and later lieutenant colonel. In 1918, following the armistice, he resumed his office at Meudon until 1926 when its administration merged with that of the Paris Observatory, Mouchez assuming the role of director of both institutions until his retirement in 1929.
He remained active in research right up until his death. Fellow astronomer Raymond Michard observed that In his bearing, his character and his style of life Deslandres always remained more akin to the soldier (and the officer) than to the scholar.
