Jessica den Oudsten works as a researcher on sailors’ biographies. As an intern at the Huygens Institute for the History of the Netherlands, she previously worked on a manual data linkage pilot, piecing together lives and careers of sailors from data observations in the Dutch East India Company’s pay ledgers, the Prize Papers and Wiewaswie.nl, a collection of Dutch genealogical data resources. She was also responsible for social media outreach for the Dutch Prize Papers online project (see for example the project’s Twitter feed). 

Melvin Wevers works as a postdoc researcher at the Digital Humanities Lab of the Royal Netherlands Academy of Arts and Sciences Humanities Cluster.

Kristof Loockx is a visiting researcher at the Huygens Institute for the History of the Netherlands. In the context of the Maritime Careers project and under the supervision of Jelle van Lottum, the aim of his research is to reconstruct careers of Dutch seafarers in the Belgian fleet, and vice versa. Kristof specializes in nineteenth- and early-twentieth-century social history, with a particular focus on maritime, labour and migration aspects. He received his PhD from the Universiteit Antwerpen and Vrije Universiteit Brussel in 2020 with a thesis entitled ‘From sail to steam: Two generations of seafarers and the maritime labour market in Antwerp, 1850-1900’. He is currently also involved in the B-magic project, where he researches seamen’s institutions and their use of the lantern projector as a tool to inform, educate and entertain seafarers within an international perspective between 1880 and 1930.
