Career

Thekla Susanne Ragnhild Resvoll was born as the daughter of Hans Resvoll and Julie Martine, b. Deichmann, born. The flora of the mountains aroused her special interest at a young age. When Thekla was seven years old, the family moved from Vågå to Oslo . Thekla Susanne passed her Abitur there in 1892. She then worked for a year as a governess for an upper-class family in Stockholm . In 1893 she began studying natural sciences in Oslo, among others with Axel Blytt , who became her mentor. She chose botany as her major . After graduating in 1899, Resvoll traveled to Copenhagen to study . In 1902 she received a position as Amanuensis (assistant professor) at the botanical laboratory of the University of Oslo , which she held until her retirement in 1936. In 1918 she received her doctorate in natural sciences. The topic of her doctoral thesis dealt with the adaptation mechanisms of mountain plants to cold and short summers.

Her sister Hanna Resvoll-Holmsen was also an important Norwegian botanist and politically active for women's rights and landscape protection. Her biographer Bredo Berntsen therefore called her one of the first Norwegian green stockings (after blue stockings ).

Thekla Resvoll was married to the mining engineer Andreas Holmsen (1869–1955). Despite criticism from her employer, she kept her maiden name in the marriage. The marriage resulted in a son in 1905.
