"August Strindberg was influenced by the Danish individualistic philosopher Kierkegaard while a student at Uppsala University (1867–1870) and mentioned him in his book "Growth of a Soul" as well as "Zones of the Spirit" (1913). Edwin Bjorkman credited Kierkegaard as well as Henry Thomas Buckle and Eduard von Hartmann with shaping Strindberg's artistic form until he was strong enough to stand wholly on his own feet." The dramatist Henrik Ibsen is said to have become interested in Kierkegaard as well as the Norwegian national writer and poet Bjørnstjerne Bjørnson (1832–1910) who named one of his characters Søren Pedersen in his 1890 book "In God's Way". Kierkegaard's father's name was Michael Pedersen Kierkegaard.
