Walter Jacob Hollenweger (born 1927 in Antwerp died August 10, 2016) was a Swiss theologian, recognized as an expert on worldwide Pentecostalism. His two best known books are The Pentecostals (1972) and Pentecostalism: Origins and Developments Worldwide (1997).
In 1955 he began studying at the Faculty of Theology of the University of Zurich. He wrote a ten volume doctoral dissertation Handbuch der Pfingstbewegung (Handbook of the Pentecostal Movement) published in 1966. The core of this work was published in various languages and became a standard work on Pentecostalism. His numerous publications in the years following made him one of the premier interpreters of this movement.
Hollenweger, who served as the first Secretary for Evangelism in the Division of World Mission and Evangelism of the World Council of Churches from 1965 to 1971, long continued to be a staunch advocate of ecumenism for Pentecostal churches.
The Hollenweger Center at VU University, Amsterdam, was established in his honor as an academic platform for and across different disciplines within the field of Pentecostal/Charismatic studies, providing opportunities to study Pentecostalism on MA and PhD level (theology, missiology, religious studies, anthropology of religion).
