He was appointed assistant on the Dutch Gold Coast on 1 October 1815, as part of the new colonial administration under governor-general Herman Willem Daendels, and became bookkeeper and cashier on 10 April 1821.
[3] The purpose of this mission was to secure the loyalty of Elmina and of the Dutch to the Asante Empire, which at the time embroiled in increasingly escalating tensions with the British.
[12] Last reported back to the Ministry of Colonies that recruitment had not only proved problematic because of the short time window, but also because voluntary emigration was an unfamiliar concept in the region.
[15] After having been in charge of the colony for three and a half years, Last left the Gold Coast in April 1832 for health reasons and was succeeded in quick succession by three interim commanders, two of whom died in office.
[17] Last had at least two children with the Euro-African innkeeper Elisabeth Atteveld: Frans Friedrich Ludwig Ulrich Last (1822–1883), who would move back with him to Kampen in the Netherlands and who would later become Attorney General at the Supreme Court of the Dutch East Indies, and Herman Willem Frederik Last (1825–1850), who remained on the Gold Coast.
