How did Eyvind Johnson contribute to the Swedish autobiographical novel?

Eyvind Johnson played a significant role in the development of the Swedish autobiographical novel through his four-volume series Romanen om Olof (1934–37).12

In this work, Johnson drew upon his own experiences as a logger in the sub-Arctic to explore the origins of human frustration. By documenting his personal history, he helped establish a foundation for the autobiographical genre in Swedish literature, a development that was also supported by the works of Harry Martinson and Agnes von Krusenstjerna during the same period.12
