Johan Wilhelm Dalman

Johan Wilhelm Dalman (November 4, 1787, in Hinseberg, Västmanland – July 11, 1828, in Stockholm) was a Swedish physician and a naturalist.

Dalman's main interest lay in entomology and botany, but he also became involved in the systematics and taxonomy of trilobites.

Dalman had drawn attention to the weakly defined axial furrows in the Ordovician trilobite Nileus.

The trilobite genus Dalmanites in the order Phacopida was named in his honour.

[1] He was the author of De narcoticis observations (1816), Förteckning paa Skrifter i medicinska vetenskaperna, samt i kemi och Naturalhistorie, utgifne i Sverige åren 1817, 1818 and 1819 (1820), Om Palaeaderna, eller de så kallade Trilobiterna (1827) and very many works on entomology.
