The name was made popular with its mention in Allen (1899)[1].

The star was observed on 2 December 1722 by the German theologian and scientist Johann Georg Liebknecht (1679-1749). He thought he observed relative motion (proper motion) to the neighbouring stars, Mizar and Alcor, and, therefore, mistook it for a planet. Subsequently, he named it after Louis V, Landgrave of Hesse-Darmstadt. Unknown to Liebknecht, it had been previously observed by the Italian mathematician and Benedictine monk Benedetto Castelli (1578 – 1643) in 1616.[3]
