What is "saeroen"

Saeroen ( Perfected Spelling: Saerun; fl. 1920s–1962) was an Indonesian journalist and screenwriter. Born in Yogyakarta, he became a journalist after a time working at a railway station. By the mid-1930s he had established the daily Pemandangan with Raden Hajji Djunaedi and was writing editorials with the pen name Kampret. When the paper was dissolved, Saeroen drifted into the film industry as a writer, making his debut with Albert Balink's Terang Boelan (1937). Much of his later life was spent working with several minor publications.
