This could only be appreciated in full after the Romanian Revolution, when Petru Andrei made it his mission to preserve and publish his father's writings. In 1990, on the occasion of the 50th anniversary of his death, the private Petre Andrei University of Iași was founded. In January 1991, he was elected a titular post-mortem member of the Romanian Academy. His diary was published at Iași in 1993.
