John Landquist (3 December 1881 in Stockholm – 2 April 1974 in Danderyd) was a Swedish literary critic, literary scholar, writer and professor of pedagogy and psychology at Lund University from 1936 to 1946.
When Landquist studied at Uppsala University, he was a member of the student organization Les quatre diables together with Sven Lidman, Sigurd Agrell and Harald Brising.
[1] Landquist was engaged in Strindbergsfejden and released August Strindberg's works.
In 1916 he wrote a monograph on Gustaf Fröding and was ready to introduce Sigmund Freud's theory of manners into Swedish literary history.
[2] Landquist's critical review of the 1946 book Pippi Långstrump was the beginning of a newspaper debate where people protested against Astrid Lindgren's manner of writing children's books.
