Eugen Rosenstock-Huessy (1888–1973) was a central force in the work on adult learning in Germany in the 1920s. He was a leading person in the first theoretical, academic reflections on adult learning, and implemented his theories in practical actions. Even if his comprehensive work has influenced key figures in the field of adult learning in the inter-war and post-war period, he is strikingly invisible in the literature of the field.
