David Friedrich Weinland

From 1855 he conducted scientific investigations in Canada, Mexico and the Caribbean (especially Haiti) and worked for three years in Louis Agassiz's microscopical laboratory at Harvard University.

[1] In 1859 he returned to Germany as director of the Frankfurt Zoological Garden; in this capacity he edited the journal "Der Zoologische Garten".

[3][4] In 1881 Weinland, writing in the popular geographical journal Das Ausland,[5][6] asserted the correctness of Hahn's attempt to classify the inclusions of the chondrites as organic, although slightly modifying Hahn's original assignment of the genera, by stating that the chondrites are in fact nothing but fossiliferous rocks, i.e. the petrified remains of life-forms.

He published in 1882 a treatise entitled Ueber die in Meteoriten entdeckten Thiereste in which he established sixteen new genera, each with multiple species.

[7] Weinland's novel Rulaman of 1878 became a bestseller of youth literature in Germany, with half a million copies sold until today.
