Christoph Friedrich Otto

Christoph Friedrich Otto (4 December 1783 – 7 December 1856) was a German gardener and botanist.

He was born in Schneeberg, Saxony. From 1805 to 1843 he was inspector of the Botanical Garden in Berlin. Together with Albert Gottfried Dietrich (1795–1856), he edited the Allgemeinen Gartenzeitung from 1833 until his death in 1856 in Berlin.

The genus of plants Ottoa H.B.K. is named after him. As a taxonomist, he was the binomial authority/co-authority of many species, including numerous plants within the family Cactaceae.
