Captain Jan (Dutch: Hollands Glorie) is a 1940 novel by Dutch writer Jan de Hartog.The book depicts highly skilled tugboat sailors as modern successors to the bold navigators of the Dutch Golden Age. It was made into a Dutch TV series in 1976. To some degree, the fictional company depicted in the book is inspired by the real-life tugboat shipping company Smit-Wijsmüller, with which de Hartog took a temporary job at in IJmuiden a few months before the German invasion - which quickly came to an end when the tug was captured by the Germans.
