30 March 1789|
|Died||17 December 1844
insane asylum, Prague
Franz Sieber was born in Prague on 30 March 1789. After 5 years of study at the Gymnasium, endowed with a considerable talent for the graphic arts, he studied architecture, switched to engineering and finally settled on natural history, in particular botany.
He made several collecting trips to Italy, Crete, Greece, Egypt and Palestine followed by a two-year-long expedition to Australia, Mauritius and South Africa, collecting not only plants, but also animals, art and ethnographic objects. He spent seven months in Sydney (then more usually called Port Jackson) from 1 June 1823 until December 1823 where he collected 645 local plant specimens.
He never reached the Western hemisphere (in contradistinction to Friedrich Wilhelm Sieber, an employee of Johann Centurius Hoffmannsegg), but sent several people to make collections for him, notably Franz Kohaut in the Antilles and Wenceslas Bojer on Mauritius.
Later life and death
His behavior and publications became progressively more erratic. He was constantly involved in quarrels with the authorities and rapidly became more and more deranged. Having “discovered” a cure for rabies he appeared in front of the city elders of Prague and demanded financial support. Soon thereafter he landed in the Prague insane asylum, where he spent the fourteen final years of his life, dying there at the age of fifty-five.
He is commemorated in the genus Siebera J.Gay (Asteraceae), and many species, e.g. Acacia sieberiana, DC, Pleurothallis sieberi Luer, or Allium sieberianum Schult.f., Crocus sieberi, Phyteuma sieberi, Luzula sieberi, Eucalyptus sieberi, Cheilanthes sieberi, Callistemon sieberi, Badula sieberi, and Hosta sieberiana, though some of these names may also have honored Friedrich Wilhelm Sieber.
