Born in Bosanci, a village south of Suceava in the Duchy of Bukovina, he came from an old Romanian family of the Storojineț area, originally called Sava.
Due to rising nationalist sentiment, family members decided to change their Ukrainized or Polonized name of Sauciuc to the unmistakably Romanian one of Săveanu.
These appeared in specialty publications domestically and abroad, such as Analele Dobrogei, Viața Românească, Revista istorică română, Buletinul Comisiunii Monumentelor Istorice, Studii și cercetări de istorie veche and Revue des études sud-est européennes.
He wrote about Greek and Latin epigraphy, archaeology, history, numismatics, hardstone carving, ancient metrology and heraldry.
Elected a corresponding member of the Romanian Academy in May 1945, he was purged in 1948 by the early communist regime and reinstated posthumously in 1990.
Due to his political activity, he was incarcerated by the regime at Sighet Prison from 1950, securing release in October 1956.
