In the 1940's and 1950's Gerard A. Zegwaard was a Missionary of the Sacred Heart in the Asmat and Mimika Region of Netherlands New Guinea (Papua Barat). His article "Headhunting Practices of the Asmat of Netherlands New Guinea" (American Anthropologist, 61(6), 1959: 1021-1041) is a highlight on his list of publications. Almost all of his posthumous writings, including more than 200 unpublished texts, are now present at the Catholic Documentation Centre (Katholiek Documentatie Centrum) in Nijmegen, Netherlands, and can be consulted there.
