After World War II, he moved to Italy, where he took on the surname Corti, and finally began to study German and Romance philology at the University of Innsbruck.
Initially aired by the ORF Ö3 entertainment radio station, Corti's commentaries in a feuilleton style and his sounding voice stood out of a mainly light music programme.
The last Schalldämpfer was broadcast three days before his death, featuring the life and work of Rabbi Hillel the Elder.
The next year he adapted Milhaud's/Cocteau's Le pauvre matelot (The Poor Sailor) and Angelique by Jacques Ibert (starring Mimi Coertse) for an enactment by the Vienna State Opera ensemble at Hofburg Palace, conducted by Hans Swarowsky.
Since 1997 an annual Axel-Corti-Preis for outstanding TV productions is awarded by several Austrian adult education associations.
