Naomi Feinbrun-Dothan (17 April 1900 – 8 March 1995) was a Russian-born Israeli botanist, who became part of the academic staff at the Hebrew University of Jerusalem.

Instead a relative helped her by testifying to the authorities that she had been a high-school student at the Herzliya Hebrew Gymnasium in Tel Aviv before leaving for Moscow for a few years.

After receiving a recommendation from Rachel Katznelson, Feinbrun started work as a teacher at a school in Tel Adashim in the Jezreel Valley.

[4] In 1926, she attended the Institute of Agriculture and Natural History in Tel Aviv, (which was directed by Otto Warburg)[6] She then accepted the part-time post of guest researcher.

[7] The first series issued in 1930 is entitled Flora exsiccata Palaestinae a sectione botanica Universitatis Hebraicae Hierosolymitanae edita.

Due to Feinbrun's cytology work with Hannan Oppenheitmer (who was engaged in physiological botany in Rehovot Campus of the university) she began teaching genetics.

[4] In 1931, she went to the Kaiser Wilhelm Institute in Berlin in order to increase her knowledge of genetics and there she worked in the 'Department for Hereditary Research'.

[4] In 1931, Alexander Eig founded the Jerusalem Botanical Gardens on Mount Scopus, together with Michael Zohary and Feinbrun.

[11] In 1933, Feinbrun joined a delegation of seven Hebrew University scientists who were invited to Iraq by the Iraqi Ministry of Agriculture.

Other research expeditions in which Feinbrun participated were to Transjordan, the Sinai Peninsula, Lebanon, Cyprus and, in 1944, to the eastern desert in Egypt.

After his death, his two assistants, Michael Zohary and Naomi Feinbrun, continued his work of documenting the flora of Palestine and cultivating the Mount Scopus Botanical Garden.

She devoted her full attention to the study of local and Middle Eastern species, mostly grown in her experimental plots and investigated cytotaxonomically (a branch of taxonomy in which chromosome characteristics are used to classify organisms).

She joined Elisabeth Oldschmidt, Tscharna Rayss and Hanna Rozin (in various fields of biology and medicine), who were the only three women of that rank in the university.
