Laan was the son of Jan Cornelis Laan and the grandson of Teunis Crok, the founders of the oil and fat processing company "Crok & Laan" (since 1971 part of Unilever). The Laan family moved in 1902 to Bloemendaal. Dick Laan started working in his father's factories in Wormerveer, and was included in the company's direction in 1916.
When production at this factory temporarily dwindled during the First World War, he started spending more and more time on his main hobby, filming. He made his first movie in 1917 and another 50 movies and documentaries followed. He was the first to make children's movies, filmed with children he knew from his football club, Koninklijke HFC, and the scouting club De Zwarte Pijl where he was a Scout Leader.
In 1927 he founded with several other directors the Dutch Film Collective (De Nederlandsche Filmliga) (See nl:De Nederlandsche Filmliga).
His writing of screenplays for movies led to the writing of books. He first wrote a number of boy's juvenile (adventure) books
However Laan is by far best known for his Pinkeltje series of children books, featuring a pinky-sized hero. The first book was published in 1939 and went on to sell 3 million copies in Dutch. He would write another 28 entries in the series, though the last four volumes were published only posthumously. Translations of Pinkeltje have been made in English, Chinese, Danish, Finnish, French, German, Norwegian, Portuguese, Swedish and Icelandic.
In popular culture
In 1978, 5 years after Dick Laan's death, Harrie Geelen directed and wrote the screenplay for a movie about Pinkeltje, which was quite successful in the Netherlands and starred Aart Staartjes as Pinkeltje and Wieteke van Dort as his female companion Pinkelotje.
Pinkeltje's popularity in the Netherlands is witnessed by the forty-plus nursery schools and kindergartens named Pinkeltje, Pinkelotje or after another character from the books.
In Heemstede, where Laan spent the last years of his life, a street was named the Dick Laanlaan (laan = lane) in his honor, later changed to the "Laan van Dick Laan". Almere has also a Dick Laan street and in his birthplace Wormerveer is a Dick Laan square.
