Peter Ludwig Mejdell Sylow
Peter Ludwig Mejdell Sylow (IPA: /peːtær lʉdviː meːdəl syːlɯːʋ/; 12 December 1832 –7 September 1918) was a Norwegian mathematician, who proved foundational results in group theory. He was born and died in Christiania (now Oslo).
He was a school teacher in Frederikshald, from 1858 to 1898. He was a substitute lecturer at Christiania University in 1862, covering Galois theory; he posed then the question that was to lead to the Sylow subgroups and his theorems about them. He published the Sylow theorems in 1872.
