Ferdinand Joachimsthal was a German mathematician.

He was born on March 9, 1818, at Goldberg (Złotoryja), Silesia and died on April 5, 1861, at Breslau (Wrocław). In the year of his graduation (Ph.D., Berlin, 1842) he was appointed teacher at a ''Realschule'' in Berlin, and in 1846 was admitted to the philosophical faculty of the university as ''privatdozent''. 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. Provided by Wikipedia
