Piet Hagen
Pieter Jacobus Hagen (1942) is a Dutch journalist and non-fiction author, who started his career as a reporter for the national newspaper Trouw in 1967. Later he served as teacher and dean of the School of Journalism in Utrecht (1983–1995), editor-in-chief of De Journalist/Villamedia (1995–2002), and columnist for NRC Handelsblad (2003–2005). He has been publishing non-fiction books since 1982, and has been a full-time author of history books since 2002. In his books on blood transfusion (1982 and 1993) he criticized the commercialization of human blood and plasma components. In 2010, he published a biography of Dutch politician Pieter Jelles Troelstra, for which he was awarded the triennial Dr. Joast Halbertsmaprijs in the Dutch province of Friesland in 2012. His overview of colonial wars in Indonesia (2018) offers a new perspective on the past five centuries: military violence was the backbone of colonialism. Bibliography
