Otto Bütschli (1848–1920) – professor of zoology and palaeontology at Heidelberg University, made fundamental contributions to cytology and the investigation of unicellular organisms, first of all ciliates. Bütschli was the first to recognise and to demonstrate that conjugation of ciliates was not a reproductive process but a sexual reorganisation of the cell similar to cross-fertilisation.

This 2000-page critical review of contemporary knowledge actually established protozoology as an autonomous discipline. Moreover, in 1875, Bütschli was the first to identify and determine the sequence of the stages of nuclear division (mitosis) in several types of animal cells. He provided excellent descriptions of dividing cells.

Abstract
Otto Bütschli (1848–1920) – professor of zoology and palaeontology at Heidelberg University, made fundamental contributions to cytology and the investigation of unicellular organisms, first of all ciliates. Bütschli was the first to recognise and to demonstrate that conjugation of ciliates was not a reproductive process but a sexual reorganisation of the cell similar to cross-fertilisation. His protozoan studies culminated in a three-volume monograph (Bütschli, 1880–1882, 1883–1887, 1887–1889), which also contained many of his own original works. This 2000-page critical review of contemporary knowledge actually established protozoology as an autonomous discipline. Moreover, in 1875, Bütschli was the first to identify and determine the sequence of the stages of nuclear division (mitosis) in several types of animal cells. He provided excellent descriptions of dividing cells.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
