Jacobson, Edward Richard


(Source: Flora Malesiana ser. 1, 1: Cyclopaedia of collectors)


Born: 1870, Frankfurt a/M, Germany, from Dutch parents. Died: 1944, Semarang, Java.



Came to Java in 1892, being in business (firm of Jacobson-van den Berg) till 1910. His entomological and zoological collections date from the year 1904; after 1910 he wholly devoted himself to the study of nature. In 1917 he settled at Fort de Kock, Sumatra West Coast; in 1932 he was awarded the honorary degree of Dr of Sci. by the University of Amsterdam; in 1933 he moved to Bandoeng, W. Java.

Several plants were named after him.

Herb. Bog. [BO]: large collections of orchids, partly with Groeneveldt and Theunissen (see those),6 but also many other plants and Fungi (some of the latter collected by his daughter Eleonora Jacobson); 550 nos (1-550) + material in spirit from the Benkoelen Exp. with mantri Ajoeb. The numbering is rather confused, e.g. the nos 2311-2809 were collected in 1915, the nos between 2200-2265 were collected in ± 1925-27; in later years he used low numbers again. In Herb. Leiden [L]: Fungi (coll. with van Heurn) and Sumatra phanerogams. In 1925 he sent material of Rafflesia arnoldi and Brugmansia (= Rhizanthes) lowii to the Herb. Linn. Soc. Lond. [LINN].7

In Hort. Bog.: many living orchids, presented in the course of years; in 1921 the whole of his collection, comprising 347 specimens.
