Gustav Woldemar Focke , sometimes also Gustav Waldemar Focke , (born January 24, 1810 in Bremen , † June 1, 1877 in Bremen) was a German doctor and naturalist.


Focke's parents were the notary and Bremen postal director Christian Focke (1774-1852) and Dorothee (Doris) Olbers (1786-1818), daughter of the well-known astronomer Heinrich Wilhelm Olbers . He was also a nephew of the doctor and naturalist Gottfried Reinhold Treviranus . From a young age he was engaged in botanical and other scientific studies. From 1830 he studied medicine at the University of Heidelberg , where he obtained his doctorate in 1833.

For further studies he first went to Vienna , where he made the acquaintance of the botanist Stephan Ladislaus Endlicher , who later named a plant from the Focke family of silk plants in honor of Fockea . As a result, he came to Berlin , where he became a student of Christian Gottfried Ehrenberg , whose microscopic examinations strongly influenced him. Finally, he spent some time in Halle to deepen his medical knowledge at the Krukenberg Clinic .

In 1835 Focke returned to Bremen with an excellent exam result, where he began working as a general practitioner. In addition, he assisted his grandfather Heinrich Wilhelm Olbers in his astronomical studies until his death in 1840 and dealt with microscopic examinations in collaboration with Peter Wolf and Georg Christian Kindt . Around 1838 he discovered the glass crab , which he named in honor of Georg Christian Kindt Leptodora kindtii .

In the following years Focke was also active as a diligent promoter of science in Bremen. He was a member of the Bremen Health Council, the directorate of the Society Museum and in 1844 organized a meeting of the Society of German Natural Scientists and Doctors in Bremen as technical director - alongside Mayor Johann Smidt as chairman . In 1860 he became a member of the German Academy of Sciences Leopoldina and in 1864 a founding member of the Natural Science Association in Bremen, of which he was chairman from 1869. He gave numerous lectures, but rarely published the results of his research in specialist publications.

In 1869 Focke acquired the Holdheim estate in Oberneuland . He had rare plants planted in the park of the property and a "grotto" built. Gustav Woldemar Focke died in 1877.
