Biography

edit

Hartig was born in Dillenburg. He was educated in Berlin (1824–1827), and was successively lecturer and professor of forestry at the University of Berlin (1831–1838) and at the Carolinum, Braunschweig.[1]

Hartig was the first to discover and name the sieve tube element cells (as Siebfasern - sieve fibres and Siebröhren - sieve tubes) in 1837. His zoologist author abbreviation is Hartig. He described many gall wasp species.

In 1842, Theodor Hartig described what is now known as the Hartig net, a network of fungal hyphae that penetrate feeder roots and surround epidermal cells.[2][3] The Hartig net is part of the structure of ectomycorrizae, mutualistic symbioses between fungi and plant roots.

He died in Braunschweig.

Works

edit

In collaboration with his father, Georg Ludwig Hartig, he published the work entitled, Forstliches und naturwissenschaftliches Konversationslexikon. The eleventh edition of his father's Lehrbuch für Förster, the later reprints of which he had revised, was published in 1877.

Family

edit

He was the son of Georg Ludwig Hartig (1764–1837), a German forester. His son Robert (1839–1901) was a forest scientist and mycologist who is considered the "father of forest pathology".
