Dr Jacob van der Land (1935-2011), curator of Vermes and chief marine biologist (1964-2000) in the National Museum of Natural History, Leiden (initially Rijksmuseum van Natuurlijke Historie, now part of Naturalis Biodiversity Center) acted as leader of several major marine expeditions in the Atlantic and Indian Oceans, and in Indonesia. He was also involved in the national and international organisation of marine research. In the museum he made a name as a helminthologist (working and publishing on Protista, Platyhelminthes, Priapulida, Annelida, Vestimentifera, and Tardigrada) and computer pioneer. One of his other major achievements was organizing the move of the museum from the old building in the centre of Leiden to the newly erected complex on the edge of the city. This concise obituary features a list of Van der Land’s publications after 2000, which were not included in an earlier description of his life (Van Bruggen, 2001), as well as lists of new taxa described by Van der Land and of eponyms.
