An annotated translation of Georg Stein's, 1933, a research trip to the Dutch East Indies

[Excerpt] Georg Hermann Wilhelm Stein was born in Zittendorf, Germany on 7 April 1897. He became a secondary school teacher who was self-educated in natural history. In 1930, employed by the Botanical Museum in Berlin, he travelled to the Dutch East Indies from 1931–1932. During the expedition he was accompanied by his wife Clara for whom he later named the bandicoot Echymipera clara. The highlight of his expedition was an ascent of the Weyland Range in western New Guinea, where he collected at least two mammal species, Microperoryctes murinus and Macruromys elegans, that have not been sighted before or since. The diaries of his expedition were lost during the Second World War (National Herbarium, Netherlands, no date), making the published account, translated into English here for the first time, a valuable chronicle (Stein, 1933).
