Otto Ruff
Otto Ruff was born in Schwbisch Hall, Wrttemberg. After becoming an pharmacist under the supervision of Carl Magnus von Hell at the University of Stuttgart he joined the group of Hermann Emil Fischer at the University of Berlin. Fischer was noted for his work on carbohydrates and so Ruff started his career as an organic chemist. In 1898 he published his work on the transformation of dGlucose to dArabinose, later called the Ruff degradation.
