Fr. Gerard Bruns was born on the 17 August 1932. He arrived in the Solomon Islands in September 1960 and worked as a Marist priest on Makira, Solomon Islands. Fr. Bruns took a great interest in the people of Makira and has documented much about the Kahua language and the culture of east Makira in the Solomon Islands. In 2008 he moved to the Marist Brothers at Tenaru Secondary School outside of Honiara. Fr. Bruns moved again and now lives at Tanagai parish centre close to the sea shore which has been his home ever since.

This collection includes typescript documents that Fr. Brun has written on his personal typewriter throughout more than fifty years of living in the Solomon Islands. The collection include grammars and vocabularly/dictionaries of the Kahua language. The collection also includes Fr John Espagne’s thesis on Makira religion, titled ‘Witless Trust’, written in 1953. Fr. Brun edited "Witless Trust" to make the text more readable and typed the manuscript himself, titled ‘Origins of Religion in Makira. Anthropological Investigations. Father Iron John Investigations 1918-2001’.
Also included in the collection is Fr. Brun's autobiography ‘Antipode’ (2015), his manuscript ‘Augunua, Among the Kahua’ (2011), which summarizes Espagne’s thesis and also the ideas of Lorensio Marau, a Makiran who had described origin stories and beliefs, developing syncretic approach to Catholicism and traditional beliefs. ‘Auguna, among the Kahua’ also contains kastom stories as well as insights into Makiran society. The collection also includes Fr. Brun's manuscript on "The evangelisation of Makira, 1845-1847; 1908-1960". Fr. Brun worked with Solomon Islanders and translated the Bible into the Kahua language.
