Rosenberg's best written effort was the "
Der Malayische Archipel. Land und Leute in Schilderungen, gesammelt während eines dreissigjährigen Aufenthaltes in den Kolonien". Here he writes about the famous
Javanese garden at
Buitenzorg, and describes the artifacts and customs of the people of Sumatra,
Celebes, New Guinea and the Moluccas. The illustrations in the book were mostly made from wood-engravings, based on Rosenberg's illustrations made on site.
Alfred Russel Wallace named Rosenberg in his book
The Malay Archipelago as "Dutch naturalist", "my friend", "old friend", "a German named Rosenberg", and as a person who gave him support on behalf of the Dutch Colonial Government. ==References==
