After his education at the Anholt City school, he was joined at age 20 by a fellowship of his country gentlemen Prince Constantin of Salm-Salm in the Academy of Fine Arts, Prague, where he trained as a historical painter with his teacher Joseph Bergler. Nadorp was the favorite pupil of Bergler. In 1822 he received the gold medal of the Academy. When in 1826 his mentor died, Nadorp broke his tents from Prague and returned in 1827 for a few months in his hometown district of Anholt in Isselburg.
In the fall of 1827 Nadorp traveled with his companions Prince Franz of Salm-Salm to Rome. The city of Rome drew at the time many German artists, such as Peter Cornelius, Johann Friedrich Overbeck and Julius Schnorr von Carolsfeld. Nadorp was quite fast in the group of German artists, called the "Nazarenes". He was one of the founders of the Roman Künstlerbund and the German Artists' Union. The years 1840-1850 are among his most fertile. Numerous drawings surviving.
