Leman Alexander Adolfovich
Russian geologist, traveler.
Born in Dorpat. Initial
education received under the guidance of his father, a famous
in childhood he was distinguished by inquisitiveness and a penchant
for the natural sciences.
In 1833 Lehman entered the Faculty of Natural Sciences at the
University of Dorpat, where K.M. Baer
was one of his teachers. Throughout
his summer studies, he made excursions in the vicinity of Dorpat,
conducting geological studies. Upon
graduation, Lehman joined in active expeditionary activities.
In 1837 at the invitation of Baer he took part in a
scientific expedition to Novaya Zemlya on the Krotov schooner,
becoming the first professional geologist in this archipelago. He
established the presence of Devonian and Silurian deposits here.
In 1838 he was invited to explore the Orenburg Territory as part
of the expedition of V.A. Perovsky,
in 1839 also with Perovsky, he made a trip to Khiva, and in the
spring of 1840 went to the eastern shore of the Caspian Sea, where
he received rich geological materials. Then
Lehman explored the southern slopes of the Urals, in the winter of
processing materials, and in the spring joined an expedition to
Bukhara, where he spent more than a year. This
journey introduced the learned world to the life of Bukharians.
Lehman was predicted a brilliant scientific future, but fate
decreed otherwise. Returning
to Dorpat, he died in Simbirsk, as they said, from “nervous fever”. Apparently,
the body could not stand the specified pace of life. After
Lehman remained valuable scientific materials, which in his lifetime
he did not have time to publish. He
bequeathed a part of the materials to the Academy of Sciences;
botanical collections were left to the professor of botany at the
University of Dorpat AA Bunge,
father of the future outstanding polar explorer Alexander
Alexandrovich Bunge. The
rest of the materials and travel descriptions were published by
Despite his short life, Alexander Lehman managed
to enrich the national botany with more than 180 new species and 20
previously not described genera of plants. Eighteen
plants discovered by him received his name. It
took eight years to process his botanical collection of the Russian
Academy of Sciences.
