They were purportedly taken in Japan by the French astronomer Jules Janssen and Brazilian engineer Francisco Antônio de Almeida using Janssen's ' photographic revolver'. It is the oldest "film" listed on both IMDb and Letterboxd. A 2005 study of the surviving material concluded that all the extant plates made with the photographic revolver are practice plates shot with a model, and if any of the many plates successfully exposed during the eclipse have survived, their whereabouts are unknown. Subject of the photos – 1874 transit of Venus The 1874 transit of Venus, which took place on 9 December 1874 (01:49 to 06:26 UTC), was the first of the pair of transits of Venus that took place in the 19th century, with the second transit occurring eight years later in 1882.

His mother Pauline Marie Le Moyne (1789 – 1871) was a daughter of the architect Paul Guillaume Le Moyne. Pierre Janssen studied mathematics and physics at the faculty of sciences. He taught at the Lycée Charlemagne in 1853, and in the school of architecture 1865 – 1871, but his energies were ...
