In 1856 he was appointed professor of mathematics at Halle, and in 1858 at Breslau.
Joachimsthal, who was Jewish, contributed essays to Crelle's Journal, 1846, 1850, 1854, 1861, and to Torquem's Nouvelles Annales des Mathématiques.
He is known for Joachimsthal's Equation and Joachimsthal Notation , both associated with conic sections.
