Johann August Carl Sievers

Johann August Carl (or Karl) Sievers (* 1762 with Sorrow, † 1795) was a German Botaniste , specialist in the Flore Asiatique.

In 1789, it leaves in Siberia to research Rhubarbe ( Rheum palmatum ).

Sievers reports its forwardings through letters sent of 1790 to 1795 since the the Ural, the Kirghisie and the steppes of Mongolia. Peter Simon Pallas published them in " Neuesten Nordischen Beyträgen " under the title " Correspondences of Sievers ".

During its voyages of research, Sievers wrote notes on many specimens whose Peter Simon Pallas (1741-1811) made a publication in 1795 pennies the title " Plantae novae ex herbario and schedis defuncti botanici Johannis Sievers descriptae " for the Nova acta of the academy of Saint-Pétersbourg.

The discoverer of the ancestor of the common apple tree

In 1793, it is the first to discover forests of Pommier S savages in the South-east of the Kazakhstan. This zone, today smaller, is always a refuge for the species Malus sieversii from now on threatened of extinction. The sudden death of Sievers at 33 years prevented it from describing this species and it is Carl Friedrich von Ledebour (1785-1851) which completed its work later 30 years.
