Johann Theodor Kleinschmidt (6 March 1834 in Wolfhagen – 10 April 1881 in Utuan, Duke of York Islands, Bismarck Archipelago) was a German trader, explorer and naturalist. He sometimes anglicised his name as John Theodore Klinesmith. He worked for the J. C. Godeffroy and Sohn and collected natural history specimens for Museum Godeffroy as well as some European collectors. He was murdered on the island of Utuan in New Britain.
Biography
Kleinschmidt was the son of Georg (1806–61) and Amalie van Heyken (born 1810). He trained as a mechanic at Kassel and worked for the Main Weser Railways at the age of 18. He also trained as an artist and then as a sailor and moved to the United States of America in 1843 but had to give up due to short-sight. He launched out in business in Saint Louis (Missouri) while also showing skills as an artist. He suffered losses during the Civil War when he served as a major between 1861 and 1865 and went bankrupt. He then left for Australia then on to Fiji to flee his creditors.
This brief starts where responsible research should: with the source description of “Theodor Kleinschmidt” as german trader, explorer and naturalist (1834–1881). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as german trader, explorer and naturalist (1834–1881). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 11, 2025. The linked authority identifier is Q1522827. VIAF identifies the subject as 80470524. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1834, 1881, 1806 and 1810.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
