Ritschl was born in Großvargula, in present-day Thuringia. His family, in which culture and poverty were hereditary, were Protestants who had migrated several generations earlier from Bohemia. Ritschl was fortunate in his school training, at a time when the great reform in the higher schools of Prussia had not yet been thoroughly carried out. His chief teacher, Spitzner, a pupil of Gottfried Hermann, divined the boy's genius and allowed it free growth, applying only so much either of stimulus or of restraint as was absolutely needful. After a wasted year at the University of Leipzig, where Hermann stood at the zenith of his fame, Ritschl passed in 1826 to Halle.
