Leman Alexander Adolfovich 
(18.05.1814–30.08.1842)

Russian geologist, traveler. 
Born in Dorpat. Initial education received under the guidance of his father, a famous doctor. Already 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 1840–1841  spent 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 Lehman’s comrades.

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.
