    Reconstructing the career of a 20th-c sailor: the case of Wilfried Julius Lackin

    In an earlier post, we explained our methodology for reconstructing careers of sailors from 18th-c data. In this one, Daniël Tuik, researcher on our ongoing Sailors on Dutch merchant marine in the 19th and 20th centuries project, tells about his work with the personnel files of the Koninklijke Nederlandse Stoomboot-Maatschappij (KNSM), a company that operated mainly from Amsterdam between 1856 and 1981. Jigsaw puzzle Reconstructing a career is essentially like putting a large jigsaw puzzle back together. There is no clear overview, because the available information is fragmented across different archival records. As an example I will reconstruct the career of Wilfried Julius Lackin, which is notable for both its…

    Visualizing networks and careers

    We mostly post map visualizations of our historical data on sailors, but we’re working on other visualizations to gain insight into our data as well. Markov models We’ve teamed up with DHLab and Marijn Koolen (@marijnkoolen) of the KNAW-Humanities Cluster to do a thorough analysis of sailor’s careers. As a first step, Marijn produced Markov model visualization of all steps in the career data we reconstructed from the digitized VOC pay ledgers. These visualizations give very good insight into the data. The one pictured below, for example, shows the various ranks from which crew members were promoted to ‘skipper or master’ and the most frequent career steps after having served…

    Daniel Engel: a maritime career reconstructed

    Daniel Engel was a young man from ‘Dantsig’ (modern-day Gdańsk in Poland) who travelled to the Dutch Republic in the mid-18th century to apply for a job with the Dutch East India Company (VOC). We’ve written about him before (in this blog post, where we introduced the Company’s pay ledgers, one of our main data sources) and now come back to him once more. Not that Engel is so special–on the contrary, there were thousands of men like him in the ranks of the VOC–but because his story is a good case in point for illustrating our work on reconstructing maritime careers. 1766: first journey to the East Indies A…

    How do we reconstruct sailors’ careers?

    We published a paper on our methodology of reconstructing sailors’ careers in the HUMIGEC project. It’s called ‘Small Lives, Big Meanings. Expanding the Scope of Biographical Data through Entity Linkage and Disambiguation’ and was co-authored by Lodewijk Petram, Jelle van Lottum, Rutger van Koert, and Sebastiaan Derks. The paper was originally presented at the 2017 edition of the Biographical Data in a Digital World conference, held in Linz, Austria. The maritime dataset and career reconstruction methodology serve as a use case to introduce the Huygens ING digital biographical data policy.
