Remco Wouter Campert was born in The Hague, son of writer and poet Jan Campert, author of the poem De achttien dooden, and actress Joekie Broedelet. His parents separated when he was three years old, causing him to sometimes live with either of his parents and sometimes his grandparents, depending on situations and circumstances. His father died in 1943 in a Nazi concentration camp, Neuengamme. Remco then went to live with his mother. They returned to Amsterdam after World War II in 1945, after having spent the three preceding years in the town of Epe.

Campert married Freddie Rutgers in 1949, but they separated five years later. In order to finance his living, Campert resorted to writing commercial texts or jingles as well as translating foreign literary works. He later married author Fritzi ten Harmsen van der Beek (daughter of comics artist Harmsen van der Beek ), with whom he lived in Blaricum until 1957, when he returned to Amsterdam. He divorced his second wife and married Lucia van den Berg in 1961. They moved to Antwerp in 1964, but Campert returned to Amsterdam two years later. There, he met art gallery owner Deborah Wolf, with whom he lived until 1980.

In Amsterdam, he started a secondary education at the Amsterdam Lyceum, occasionally writing articles or drawing comics for the school’s newspaper. As the years went on, he skipped more and more classes and spent increasing amounts of time in cinemas, jazz clubs or pubs. He finally left school without graduating. With Rudy Kousbroek, a school friend, he founded the magazine Braak in May 1950. Between 1949 and 1952 Campert drew cartoons for the Dutch magazine Mandrill and Het Parool and in the 1970s for Haagse Post too. In 1979 he drew comics for NRC Handelsblad.

He resumed writing in 1979. He wrote Somberman’s actie in 1985. From 1989 until 1995, Campert starred in theatres throughout the nation and beyond in a play he had created together with Jan Mulder (author and ex-football player). Their shows were based on both their literary works. 1995 was also the year he read his bestseller novel ‘Het leven is vurrukkulluk’ on the radio.

He has mostly kept quiet about his life in the following years, however, he once explained his situation in 1994, in an interview to Cees van Hoore, journalist of newspaper ‘Nieuwsblad van het Noorden’. He was quoted as saying; “I don’t choke myself. I’m my own best company. Whenever I lived together with someone, I felt like being underwater for days on end. To be together is to be twice alone and I don’t need that. I’m more than happily married to my career.”
