Koningsberger was born in
Hazerswoude, South Holland, Netherlands, on 17 January 1867. The son of Victor Jacob Koningsberger, a minister with the
Dutch Reformed Church, and Josina Cornelia Tieleman, Koningsberger moved to
Utrecht in 1871. He completed his studies in that city, ultimately receiving a degree in biology from
Utrecht University in 1889; he also studied mathematics. After some time as an assistant to the botanist N.W.P. Rauwenhoff, on 28 October 1891 Koningsberger defended his doctoral thesis:
Bijdrage tot de kennis der zetmeelvorming bij de angiospermen (
Contribution to the Knowledge of Starch Formation in Angiosperms). In 1894, after teaching botany and zoology in
's-Hertogenbosch, Koningsberger departed for the
Dutch East Indies. In the colony, he focused primarily on the pests that affected coffee cultivation; he produced a two-volume treatise on this subject,
De dierlijke vijanden der koffiecultuur op Java (
The Animal Enemies of Coffee Culture in Java, 1897 and 1901). By 1898 he was working for the
Lands Plantentuin in
Buitenzorg (now the Bogor Botanical Gardens in Bogor) under
Melchior Treub. He was entrusted with the Xth Department for Agricultural-Zoological Research, and in 1894 he established the
Landbouw Zoologish (now the Bogor Zoology Museum). Koningsberger returned to the Netherlands in 1899, but had begun working the Indies again by the early 1900s. During this second period in the Indies, Koningsberger wrote several papers on
crop diseases. He also produced a twelve-volume text on the flora and fauna found in
Java,
Java, zoölogisch en biologisch (
Java, Zoology and Biology); this was the first zoological profile of the island. During this period, Koningsberger promoted
nature conservation in the Indies, and his influence facilitated the passage of the colony's first conservation law in 1910. In 1910, Koningsberger was appointed the director of the Lands Plantentuin. During his leadership, a conservation area was established in
Sibolangit,
Deli Serdang, in 1914; it has since become a
botanical garden. He was a vocal proponent for using "pure" science, arguing in one speech that "every contribution that further adds to the knowledge of this land's nature – still so very secretive in many ways – can only contribute to increasing the inviolability of our bill of ownership". Koningsberger spent some time as the administrator of the Landbouwschool (now part of
IPB University). Between 1915 and 1916, he acted on behalf of
Hermanus Johannes Lovink as the director of the Indies' Department of Agriculture, Industry, and Trade; he wrote that he preferred his position with the Lands Plantentuin, as it had fewer administrative challenges. ==Political career==
