In 1819 he sent his first works ("Reposing Venus", "Portrait of Csokonai", "Shepherdess or the Beginning of Fine Crafts") to Hungary and they brought him several scholarships and, as a result, he became Canova's pupil for two years.
Inspired by his progressive artistic education, Ferenczy returned to Hungary in 1824. where by the 1830s he had modelled the portraits ("Ürmélyi", "Rudnay", "Kazinczy", etc.), tombs ("Kulcsár", "Szánthó", "Fornay", ), and altarpieces ("The Blessed" in Vál, "The Martyrdom of St. Stephen" in Esztergom,) and some smaller memorials ("Károly Kisfalady" in Muzeumkert, Budapest).
It was Ferenczy who discovered marble in Ruszicka. Travels and excavations cost his much of his fortune. He completed the "Statue of Kölcsey", his major work in 1846 but retired from larger sculpture work from 1847 onwards. Only the statue of "Eurydike", one of his best works, and small clay statuettes occupied in his time in the 1850s.
