Was it Robert Jonckheere’s passion that ignited the spark for this very Observatoire de l’Institut de mathématiques appliquées et d’astronomie? It stands here a monument to both scientific curiosity and human dedication. Welcome.
The Observatoire de Lille is more than just a building. It is a gateway to the cosmos. This is a place where the mysteries of the universe are explored.
Our journey begins with Robert Jonckheere. He was a Roubaix native born in 1888. Jonckheere was an astronomy enthusiast. He founded his own observatory in Hem. That initial observatory opened its doors in 1909. It featured a 9-meter dome. It also contained a telescope with a 35 cm diameter lens. Its focal length was over 6 meters. Jonckheere also diligently recorded meteorological data. He also provided timekeeping services.
The First World War disrupted Jonckheere’s work. Hem fell under occupation. He sought refuge in England. There he worked at the Royal Observatory in Greenwich. Upon his return, hardship struck. He had to sell his equipment to the University of Lille. The original buildings were demolished in 1934.
The city of Lille stepped in. Mayor Roger Salengro spearheaded the construction of new scientific facilities. This included a new observatory. It would house Jonckheere’s salvaged telescope.
Marcel Boudin designed the current Observatoire de Lille. He was a student of Robert Mallet-Stevens. Construction finished in 1932. It officially opened on December 8, 1934. The Observatoire de Lille has been a historic monument since November 15, 2001.
The Observatoire de Lille features a museum. Inside are scientific instruments. These tools were used in meteorology and astronomy. They include anemometers and barometers. Sextants and micrometers are also part of the collection. You’ll also find receiver sets and various clocks.
The dome stretches approximately 16 meters high. It houses a telescope. Its lens is 325 mm in diameter. The focal length is 6 meters. This makes it one of the largest in France. The telescope has a CCD HiSys22 camera.
The Observatoire de Lille continues its mission. It focuses on teaching and sharing knowledge. It also conducts research. Currently, researchers study comets and space debris. The Observatoire de Lille also offers observation sessions. These are for students in the DU astronomy course. University staff working in the building can also attend.
Think of the countless stars observed here. Picture the discoveries made within these walls. The Observatoire de Lille inspires awe and wonder.
The Observatoire de Lille stands as a testament. It highlights the enduring human quest for knowledge. It encourages us to look up. It also inspires us to explore the vastness of space. Its legacy lives on through education, research, and the countless individuals. They have gazed at the heavens through its lens.
