Ochsenheimer was an excellent character actor and was compared with Iffland for his facial expression and his pronunciation. In the roles of villains he is said to have been of staggering impact, and excellent as old fogies and pedants. Among his crowning achievements were Gottl. Koke in "Parteiwut", Wurm in "Kabale und Liebe" or Marinelli in "Emilia Galotti". He also published plays, in part under the pseudonym Theobald Unklar. "In private life he was, like most comedians, melancholy, dry, bland, even boring, except when discussing entomological subjects; he also was a misogynist."
