in november of the same year, noether delivered a plenary address ("großer vortrag") on "hyper-complex systems in their relations to commutative algebra and to number theory" at the international congress of mathematicians in zürich. the congress was attended by 800 people, including noether's colleagues hermann weyl, edmund landau, and wolfgang krull. there were 420 official participants and twenty-one plenary addresses presented. apparently, noether's prominent speaking position was a recognition of the importance of her contributions to mathematics. the 1932 congress is sometimes described as the high point of her career.
