Born: 1877, Oschatz between Leipsic and Dresden, Germany. Died: 1945, Dresden, Germany.



Botanist who took his Ph.Dr’s degree in 1898 at Leipsic and was probably subsequently appointed at Tübingen. He visited the D.E.I. for the first time in 1903-04, working for several months in the Foreigners’ Laboratory at Buitenzorg for ecological and plant-geographical researches; he studied the culture of coca and cinchona also.1 Later he was appointed Professor in the University and Director of the Botanical Garden at Hamburg. In 1924-25 he paid a second visit to the D.E.I. with the main purpose of collecting material on behalf of his institute.2 The 10th volume of the ‘Mitteilungen Inst. Allg. Botanik Hamburg’ is a ‘Festschrift’ in his honour.

Several Bornean plants were named after him (cf. Backer, Verkl. Woordenb., 1936, sub johannis winkleri).
