In the period 2008-2011, I researched and wrote a manuscript exploring how Denmark had become the world's leading operator of liner services. The research spanned from the latter part of the nineteenth century, when the first Danish 'deep sea' steamship routes were established, until 2011. The work focused in particular on technological developments and on the business histories and operational contexts of the major shipping lines, DFDS, EAC and Maersk. The manuscript was published in Danish by Nautilus Forlag and was well received by reviewers. An updated English language edition is planned for 2014.
