Otto Hahn (1828 – 1904) was a German petrologist, geologist, lawyer and author.
He eventually left the legal profession for the natural sciences.
The University of Tübingen awarded him a doctorate for his participation in the Eozoön canadense controversy.
[5] His book Die Meteorite (Chondrite) und ihre Organismen,[6] published the following year in 1880, was a major work in the field of meteoritics that included 142 black and white photomicrographs of chondrite thin sections.
[7][8][9] In addition, he claimed that the iron meteorites have an organic origin and that they are the petrified remains of a fungus or plant that was permeated with iron-nickel alloys, e.g. similar to ichnotaxa like the Chondrites.
