In 1834, Friedrich Bessel discovered that Sirius periodically swings out of position, which could only mean one thing: the star is accompanied by an invisible companion. However, telescopes of the time could not detect it. The big event did not come until three decades later, in 1862, when the American optician Alvan G. Clark, a brilliant telescope designer, while testing his new 460 mm refractor in close proximity to Sirius, a faint star, later called Sirius B - also called "Puppy" in Anglo-Saxon areas. It was not until 1915, however, that its true physical nature was discovered, making it the first white dwarf ever discovered.
