Armen Leonovich Takhtajan or Takhtajian (

taxonomists
of the latter twentieth century.

Life

Family

Armen Takhtajan's father (left) and grandfather (right), appr. 1900

Takhtajan was born in

Realschule attached to the Armenian seminary, due to lack of opportunities in his chosen field. There he met and married Gerseliya Sergeevna Gazarbekyan (1887–1974), Armen Takhtajan's mother, a native of Susha, in 1909.[1][2]

Early life and education

The Takhtajans had three children, Armen (1910–2009), Nellie (1914–1994) and Nora (1918–1965). In 1918 the family were forced to flee to northern Armenia because of the

Leningrad University and attended lectures by Vladimir Leontyevich Komarov (1869–1945) on plant morphology. In 1929 he began his studies in biology at Yerevan State University in Yerevan, Armenia, which he completed in 1931. He then returned to Tbilisi, enrolling in the All-Union Institute of Subtropical Crops.[1]

In 1932 after completing his course at Tbilisi he worked for a while as a laboratory assistant at Sukhumi, Georgia, at the subtropical branch of the All-Union Institute of Applied Botany and New Crops (now the Institute of Plant Industry), before returning to Yerevan. In Yerevan he took a position as researcher at the Natural History Museum of Armenia, and then at the Herbarium of the Armenian branch of the Institute of Biology, Soviet Academy of Sciences, and began teaching at Yerevan University in 1936, while completing his Master's thesis.[1]

He died in Saint Petersburg on 13 November 2009, at the age of 99, in 2009, having just completed his most important work, Flowering Plants.[3][2]

Work

From 1938 to 1948 he headed a Department at the

National Academy of Sciences since 1971. He was also the academician of the Academy of Sciences of the Armenian SSR, the president of the Soviet All-Union Botanical Society (1973) and the International Association for Plant Taxonomy (1975), member of the Finnish Academy of Science and Literature (1971), the German Academy of Naturalists "Leopoldina" (1972) and other scientific societies.[4] He was a member of the Norwegian Academy of Science and Letters from 1980.[5]

While at the

phylogenetic relationships between plants. His system did not become known to botanists in the West until after 1950, and in the late 1950s he began a correspondence and collaboration with the prominent American botanist Arthur Cronquist
, whose plant classification scheme was heavily influenced by his collaboration with Takhtajan and other botanists at Komarov.

He is chiefly famous as the author of works on the origins of flowering plants and paleobotany, developing a new classification system of higher plants. He worked on the "Flora of Armenia" (vol. 1–6, 1954–73) and "Fossil flowering plants of the USSR "(v. 1, 1974) books. Takhtajan also developed a system of

floristic regions.(Takhtajan, Crovello and Cronquist
, 1986)

For many years restrictions were placed on his work because of his opposition to the official line on genetics promoted by Lysenko.[6] In 1993 he worked for a while at the New York Botanical Garden.[6]

Legacy

Takhtajan has been considered one of the leading botanists of his time.[2][6]

He has been honoured in the naming of several plant genera.[11] In 1980, botanist Vandika Ervandovna Avetisyan published Takhtajaniella, which is a genus of flowering plant from Transcausica, belonging to the family Brassicaceae and it was named in his honour.[12] Then in 1990, Nazarova published Takhtajaniantha (from the dandelion tribe within the daisy family,[13]) and lastly in 1997, Takhtajania (from the family Winteraceae, which was found in Madagascar) was published.[14]

The standard author abbreviation Takht. is used to indicate this person as the author when citing a botanical name.[15]
