Theodor Hartig (21 February 1805 – 26 March 1880) was a German forestry biologist and botanist.
Biography
[edit | edit source]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.
