20th-century Dutch journalists

Jan Pieter "Jan P." Strijbos (March 14, 1891 – May 10, 1983) was a Dutch naturalist, cineaste, photographer, journalist, writer and public speaker of the nature (and birds in particular) protection movement.
Strijbos grew up in Haarlem and initially worked as an architectural engineer. He became more and more interested in birds and chose to start publishing on the subject in 1927. Daily newspapers such as Het Parool and De Telegraaf frequently reserved space for his popular columns. His first major work was the first part of What's that bird called (Dutch: Hoe heet die vogel?), followed by part two in 1930. He also wrote a richly illustrated book on the breeding of the grey heron before becoming involved in photography. His most notable achievement in that field was the material he created in the pre-war great cormorant colony in Lekkerkerk. He also created visual material for the promotion of his cause, which he mainly used for his lectures. His friend and Nobel prize winning ethologist Niko Tinbergen characterised him in a preface he has written for Strijbos' 1956 book about South Africa as follows: "(...) the tramp, the carefree enjoyer, the admirer, the minstrel, and the ambassadeur of all things living, the witty conversationalist".

Anthonie "Anton" Koolhaas (16 November 1912 – 16 December 1992) was a Dutch journalist, novelist, and scenario writer.

Piet Oege Bakker (10 August 1897 – 1 April 1960) was a Dutch journalist and writer. He was joint editor for many years of the weekly magazine Elseviers Weekblad.
His most famous work was the trilogy written between 1941 and 1946 dealing with the experiences of the street urchin Ciske Vrijmoeth, alias Ciske the Rat. These novels sold in their hundreds of thousands, and later appeared in translation in more than ten other countries. The story has been filmed twice, in 1955 and 1984, and a musical version ran from October 2007 to November 2009.

Jan Greshoff (15 December 1888, Nieuw-Helvoet – 19 March 1971, Cape Town) was a Dutch journalist, poet, and literary critic. He was the 1967 recipient of the Constantijn Huygens Prize.

Hendrik Willem van Loon (January 14, 1882 – March 11, 1944) was a Dutch-American historian, journalist, and children's book author.

Simon Carmiggelt (7 October 1913 – 30 November 1987) was a Dutch writer, journalist, and poet who became a well known public figure in the Netherlands because of his daily newspaper columns and his television appearances.
