Fr Robert Kothen was one of Cardijn’s earliest collaborators from 1919 when he was recruited by Jacques Meert.
Indeed, it is likely that Fr Kothen was also one of the first, if not the first priestly vocation to emerge from the new JOC movement.
After ordination, he assisted Cardijn in making contact with other countries, particularly English-speaking countries.
He wrote many books and pamphlets including The Priest and the Proletariat published in 1948, an insightful reflection on the role of priests with the working class.
