Antheunis Janse (1890-1960) was born in Oostkapelle, he was the son of a farmer Jan Janse and Catharina Wondergem. In 1910 he became a teacher at Schoondijke, in 1917 he taught at Biggekerke and in 1918 became head of the Christian school.
In the next two decades or so he produced numerous booklets and books. Janse had asked Vollenhoven for a copy of his doctoral thesis and the conversation began from there. They published one paper together: 'De activiteit der ziel in het rekenonderwijs' (1918).
Janse was of the instigators, with Dooyewerd and Vollenhven behind the Association for Calvinistic Philosophy (1935). B. J. van der Walt notes that we should see Janse, Dooyeweerd and vollenhoven and the three joint founders of reformational thought.
His anthropology led him in conflict with the implicit scholasticism of many in the Gereformeerde churches. Janse stressed the unity of a human being which was not appreciated by the dualistic approach supported by V. Hepp, H. H. Kuyper and J. Riderbos.
During the war his house was confiscated by the Nazis in 1942 and he had to move with his family to Breda. He suffered from Parkinson's disease from 1939 onwards. He was arrested in Breda, after its liberation by the Polish, after being accused of sympathising with the Germans during the war.
He died in 1960, his last words to Telder were: 'May the Lord strengthen you in your work'.
He had a great influence upon Vollenhoven, K. J. Popma, B. Telder and C. Vonk.
