About the author

Hendrik Groen, pseudonym of Peter de Smet, is a Dutch writer. He is the author of the book Pogingen iets van het leven te maken: Het geheime dagboek van Hendrik Groen, 83¼ jaar (The Secret Diary of Hendrik Groen, 83¼ Years Old) published in 2014. That book was awarded in 2016 with the Audience Award for the Dutch Book. The sequel Zolang er leven is: het tweede geheime dagboek van Hendrik Groen, 85 jaar (On the Bright Side: The New Secret Diary of Hendrik Groen) appeared in 2016.

For years it was unknown who was hiding behind the pseudonym. This led to speculation about who it could be. Names from Sylvia Witteman to Arnon Grunberg were mentioned. Both De Volkskrant and NRC Handelsblad revealed almost simultaneously in 2016 that Peter de Smet was 62-year-old. De Smet responded with the words that 'he is not waiting for publicity' and 'has no sense in the fuss about fame'.

The Secret Diary of Hendrik Groen, 83¼ Years Old in 2016 won the Audience Award for the Dutch Book. This prize was not personally collected by the author.

In 2017, the books were filmed and broadcasted by Omroep MAX as the television series Hendrik Groen's Secret Diary. Screenwriter Martin van Waardenberg once again confirmed that De Smet was the man behind the pseudonym. In 2017, a stage adaptation was also brought to the stage under the direction of Gijs de Lange. Beau Schneider played the role of Hendrik Groen.
