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.
This person is more likely: Akte - Noord-Hollands Archief. His name is Dirk Anthonie Faber and he was born in Medan (thus Indonesia). He died aged 33 on 24 April 1959 at Den Helder, Netherlands. Death certificate attached (lower).
edit: ...Laurent and I found the same person...
Mmmm, maybe not reading through the previous posts well enough. All right, mea culpa. So here is for a better try: he did publish in 1972: http://www.sidalc.net/cgi-bin/wxis.exe/?IsisScript=cibagro.xis&method=post&formato=2&cantidad=1&expresion=mfn=026142.

His full name is William Joseph Fox: see https://ansp.org/research/library/archives/0400-0499/portraits457/?_ga=2.111056837.1192180927.1602683784-1164481084.1602683784 and scroll down to F of Fox. He was more of an entomologist according to the additional info.
Short question: Does somebody know who's commemorated in the scientific name ... macartneyi
And does it say anything additional of what he'd done, why he was given this mark of honour?
It is presumably this person (note the last sentence)...
