Rasmus Flo (29 September 1851 – 30 November 1905i) was a Norwegian teacher, philologist, magazine editor, and translator.

[1][2][3][4][5][6][7] Rasmus Flo was born in Stryn near the northern border of Sogn og Fjordane, Norway.

In 1892, he helped Molkte Moe in writing Nordahl Rolfsen's textbook, particularly with spelling and styling in the Nynorsk edition.

[4][5] As a result of this and his work on textbooks by Rolfsen and Austild, Flo had a considerable amount of influence on the development of Nynorsk.

[4][5][6] He had spent the evening putting together the next edition of Syn og Segn with a colleague and appeared to be in good health before he retired for the night.
