[Michael Rhodes]

Arthur Engel, who died 11 November 2022, aged 94, was a German mathematics teacher, educationalist and prolific author. His work has been translated into several languages. He had played a role in national and international mathematical competitions since 1970. Engel was one of the first to recognize the impact of electronic calculators and computers on mathematics teaching. He viewed that the focus should shift from learning how to apply algorithms, which could now be done by the machine, to learning how to build and test algorithms.
