Fernand Baldet : ウィキペディア英語版 | Fernand Baldet
Fernand Baldet (16 March 1885 – 8 November 1964) was a French astronomer. He worked with Count Aymar de la Baume Pluvinel observing Mars from the newly built observatory on Pic du Midi in 1909. The resulting photographs, taken with the 0.5 metre (20 inch) reflecting baillaud telescope, were so sharp, that they were able to disprove Percival Lowell's claim of geometrical canals on the planet's surface. The crater Baldet on the Moon and the crater Baldet on Mars were named in his honour. ==External links==
