In 1947, Elias joined the newspaper
De Tijd. He worked as the chief of the editorial staff and specialized in education. He covered such topics as the Secondary Education Act (or Mammoth Act) and the development of
Middenschool. When
De Tijd stopped being produced as a daily newspaper, Elias became the education editor for the
NRC Handelsblad. At both papers he wrote a column called "Notebook" ("Cahier"), which was influential. Elias also wrote regularly about concentration camps, partly based on his own experiences at Buchenwald. From 1950 to 1970, Elias wrote theater reviews for the
Katholieke Illustratie. In 1967, Elias was awarded the M. van Blankenstein Prize. In 1970 he was made a knight in the
Order of Orange-Nassau. He died on 28 October 1980. == Archive ==
