Zosterops dehaani van Bemmel, 1939 OD here

Neben seiner eigentlichen Explorationstätigkeiten fand Herr DE HAAN noch Zeit, eine kleine Vogel-Sammlung anzulegen, welche er dem Zoologischen Museum Buitenzorg schenkte.

Treron pompadora dehaani Van Bemmel & Voous, , 1951 OD here
P.S. Think should only be attributed to Voous (Article 50.1, ICZN Code)

The Eponym Dictionary of Birds claims:

Cream-throated White-eye ssp. Zosterops atriceps dehaani Van Bemmel, 1939
Pompadour Green Pigeon ssp. Treron pompadora dehaani Van Bemmel & Voous, , 1951 NCR [Alt. Grey-cheeked Green Pigeon ssp.; JS Treron griseicauda wallacei]
Gunter Adelbert Leonard de Haan (b.1911) was a Javan-born Dutch botanist. He went to the Netherlands to be educated at the Agricultural College, but left for the Dutch East Indies before completing his studies. There he enlisted in the army (1933) but soon bought himself out and joined the Teak Forest Administration (1933–1935). He later became an administrator in the Indonesian Forest Service (1936–1940), which included an exploratory tour in the Moluccas (1937–1938). At the outbreak of war he was suspended, then dismissed, because of his political opinions. After WW2 he was evacuated to Holland but returned (1948) to Halmaheira as a plantation manager, planning to use his spare time to make botanical collections for sale. He made an initial collection of 50 plants, but abandoned the idea as it was poorly received. He wrote a number of articles including 'Notes on the Invisible Flightless Rail of Halmahera' (1950). During his time at the museum Voous (q.v.) obtained a collection, made by de Haan, of 221 birds from Muna, Buton and the Moluccas.

The Key to Scientific Names

Gunter Adelbert Leonard de Haan (b. 1911) Dutch forestry officer in the East Indies 1933-1940, botanist, collector (syn. Treron griseicauda wallacei, subsp. Zosterops atriceps).

Here as well only as Haan, Gunter Adelbert Leonard de (1911-). No help eather regarding his death here but

Gunther Adelbert Leonard de Haan est né(e) le 21 octobre 1911 dans Probolinggo, Java, fils de Popke de Haan et Anna Marie Pauline Homburg.

Maybe someone here has an additional souce to find his death?

 

[l_raty]

In this (p. 7), he appears in a list of persons that were captured by the Japanese in May 1940, and imprisoned in concentration camps...

 

[Taphrospilus]

But consider according Eponym he return 1948 to Halmaheira. As well see here where he offered help for a publication from 1953. In 1950 he published in Amsterdam Naturalist.

 

[l_raty]

Yes, correct. That he publish a paper on the Invisible Rail in 1950 can also be seen here.

 

[Taphrospilus]

In this (p. 7), he appears in a list of persons that were captured by the Japanese in May 1940, and imprisoned in concentration camps...

Not the only one to whom that happened. Remember JJ Menden.

This is what I have on old info:

de HAAN, Gunter Adelbert Leonard – Dutch. B. 1911, Probolinggo, Java, Indonesia - D. After January 1955. Studied at Agricultural College, Wageningen (the Netherlands) but aborted his study to return to Java in 1933. He served here in the army, and subsequently worked for a short time for a Teak Forest Administration at Moena (southern Celebes) till the end of 1935. Since May 1936 the Indian Forest Service employed him. He remained here till 1940, and was stationed at the Forest Research Institute. In 1937-38 he was sent on an exploration tour to the Moluccas; in July 1938 stationed in Tapanoeli (N. Sumatra) and in April 1940 at Rengat (Central. Sumatra). At the outbreak of war he was suspended and subsequently dismissed on account of his political opinions. After World War II he was evacuated to The Netherlands; in 1948 he left for Kobe in Halmaheira (Moluccas) as manager of a private plantation and timber-concession. He collected in these years intensively for the Bogor Museum as for ZMA and the private collection from Johan Gottlieb van Marle. He collected at Muna (1935, 1948) and Butung (1948) at the south coast from Celebes (Sulawesi), Halmahera (1937, 1948, 1949 and 1950), Ternate (1938, 1948, 1950), Bacan (1937, 1948), Tapat (1953), Obi (1937, 1953), Morotai (1938, 1950) and Gebe (1950), the latter are all at The Moluccas. He returned to Europe by 1953, and most possibly he settled in Germany since then.

In the MS Notes after our dear, late friend Jan van der Brugge (who passed away earlier this year) I find:

dehaani (Hemiprocne longipennis, Treron griseicauda, Zosterops/Z.atriceps): Gunter Adelbert Leonard de Haan (*1911), Dutch forestry officer in the East Indies, 1933-1940, botanist, collector. in 1938. In the spring of 1938 he visited the Moluccan islands of Ternate, Halmahera and Morotai, as official of the Dutch Boschbouwproefstation on Java, for forest exploration. On Morotai he collected special forms of Pitta maxima.

Name Z. dehaani was given by A.C.V. van Bemmel in 1939, name Treron griseicauda d. [dehaani] by Voous in 1951, name Hemiprocne longipennis d. [dehaani] by S.Somadikarta in 1975.

Even if now (after Justin's post #6) maybe somewhat superfluous, that is regarding the details of de Haan's life, though Jan's MS/notes does add a third Bird [a taxon neither listed in The Eponym dictionary ..., nor in the Key] commemorating the same Mr de Haan ...

• The debated [valid, alt. invalid*] Grey-rumped Treeswift ssp. "Hemiprocne longipennis dehaani" SOMADIKARTA 1975, described in:

Somadikarta, S. 1975. On the Two New subspecies of Crested Tree Swift from Peleng island, and Sula islands (Aves : Hemiproanidae). Treubia 28 (4): pp.119–127 (= here, here, and here, all in Google Snippet View/s):

... named after ... MR. G. A. L. DE HAAN, in recognition for ...

Enjoy!

Björn

PS. The second Bird of the OD's "Two New subspecies ..." (i.e. the mendeni bird, and its dedicatee; "J. J. Menden") was earlier dealt with in the long-lasting thread (2015–2121); Mendeni and the mystery J. J. Menden (here).

---

*As far as I can tell, most often (also, just as the mendeni one) today considered a junior synonym of Hemiprocne longipennis wallacii (Gould, 1859).

 

[Björn Bergenholtz]

More info about G. A. L. de Haan is found in Flora Malesiana, vol. 1 (1950), incl. a Photo/Portrait (here), also (somewhat more) in ditto, vol. 5 (1958, here).

To me, it looks like he was still collecting (Plants), in August 1957 (here), this time on Sumatra, Indonesia.

And, note; in BBOC 123 (2003) C. S. Roselaar (who ought to be familiar with most Dutch collectors) lists him as "Haan, Günther A. L. de (Amsterdam)" (here), in connection to ZMA (Amsterdam); see here, below; "Important collections come from ... G. A. L. de Hahn, ..."

Which version of his first Given name (Gunter versus Günther) is the proper one is all unknown to me. Neither do I know if he was still alive in 1975 when Somadikarta named the Treeswift ssp. in his honour. If born in 1911, as stated above, he sure could have been, but ... who knows? Collecting Natural History specimens isn't hazard-free.

Thus, take the above for what it's worth. It's just some observations.

And; good luck finding him (in full).

[vinividivici]

Dear all,

I fear that there has maybe been a misunderstanding with regards to the nature of De Haan’s internment.
The newspaper magazine that you - Laurent - found indeed reports that De Haan has been among people captured. But upon closer reading, it is evident that it was the Dutch government in the Indies that put him behind bars. Thus Martin, this is not another example of the subsequent mass internment of European and Indo people by Japanese occupying forces in what is Indonesia.
It all gets politically sensitive - De Haan was (thought to be) a member or sympathizer of the Indies branch of the NSB (a Dutch political party sharing much of the German Nazis’ ideology), and sort of preemptively interned by the colonial Dutch government (the Netherlands by then occupied itself).
These were shipped out to an internment camp in Suriname (Jodensavanne internment camp - Wikipedia). This website seems to confirm that De Haan was among these inmates (Namenlijst gevangenen Jodensavanne - Prinses Irene Brigade).
This may plausibly explain why De Haan seems tricky to track - he may have wanted to escape further attention in the end.

 

[l_raty]

Yes, now that you explained it, this makes much more sense, indeed.
I didn't know the NSB, nor this part of Dutch history, and failed to realize what this journal was exactly.

Aha fascinating that explains why Justin thought he may have settled back in Germany. Which begs the question - Did Somadikarta know de Haan's history in honouring him or was this an inadvertent mistake? I also find that the MCZ (Harvard) took/bought a large collection from De Haan from Indonesia collected in 1950. Could he have moved to the USA? A final mystery is that between 1977 and 1980 a dozen Cetacean specimens are present in European Museums collected by a Mr G. De Haan in northern Holland.

This G de Haan refers to Gerrit de Haan who indeed worked on cetaceans on for instance Texel. Several of his finds are detailed on www.walvisstrandingen.nl (beached whales and dolphins in the Netherlands).

He is not our man. De Haan is, unfortunately, quite a common family name in the Netherlands.
