Hanna Resvoll-Holmsen

Hanna Marie Resvoll-Holmsen (née Resvoll) (11 September 1873 in Vågå, Oppland – 13 March 1943 in Oslo) was a Norwegian botanist – a female pioneer in Norwegian natural history education and nature conservation together with her sister, Thekla Resvoll.

Hanna Resvoll-Holmsen suffered much from illness in her childhood and school attendance after her 12th year was sporadic.

She studied natural history at the Royal Frederik's University in Kristiania and graduated in botany in 1910.

Hanna Resvoll-Holmsen participated as a botanist in the Svalbard expedition in 1907 led by the oceanographer Prince Albert.

Resvoll-Holmsen was first married to Hans Dieset (divorced 1901), then from 1909 to state geologist Gunnar Holmsen (1880–1976), brother of her sister's husband.
