"Carl Friedrich Wilhelm Alfred Fleckeisen (September 23, 1820 in Wolfenbüttel – August 7, 1899 in Dresden) was a German philologist and critic. He is best known for his work on Plautus and Terence.
He was educated at the Helmstedt gymnasium and the University of Göttingen. After holding several educational posts at Frankfurt am Main and Dresden, in 1861 he was appointed in the vice-principalship of the Vitzthum-Gymnasium at Dresden, which he held until his retirement in 1889. Fleckeisen is chiefly known for his labors on Plautus and Terence; in the knowledge of these authors he was unrivalled, except perhaps by Ritschl, his lifelong friend and a worker in the same field." - (en.wikipedia.org 11.08.2021)
