Claus Jansen Rollwagen , Dutch: Claes Jansz. Rolwaghen , (* around 1588 in the Netherlands ; buried on September 26, 1631 in the Grote Kerk in Alkmaar ) was a Dutch surveyor and dikemaster .

Live and act

Claus Jansen Rollwagen was a son of the dikemaster Johann Clausen Rollwagen and his wife Clara, née van der Voort. Before 1616 he married Susanna de Moll, with whom he had several children. She was a daughter of the banker Joris Jacobsz. de Mol and the Emerentia dimmer from Alkmaar.

Rollwagen's childhood and adolescence are not documented. He probably acquired sufficient knowledge of theoretical and applied mathematics in Amsterdam and Alkmaar, where his father was staying around 1600, to be able to take up the profession of surveyor. He worked for his father on the west coast of Schleswig-Holstein and was active here for the first time in the summer of 1610. In October 1610, the Gottorf Duke Johann Adolf appointed his father dikgrave general. Claus Jansen Rollwagen entered the Duke's service as a surveyor on the same day.

In September 1615 Rollwagen visited the island of Nordstrand with his brother-in-law Jacob de Moll and Jan Clausen Coott . He planned the course of a new sea dike to be built in front of Olgrof , Brunock and Stintebüll . The Duke obviously encouraged him to take over the construction work for the first time as dikemaster together with his brother-in-law. Jan Clausen Coott was accepted because of a cheaper offer. 1616 appointed the new Duke Friedrich III. Father and son carts to the dikers general. There is no evidence of Claus Jansen Rollwagen's work in the following years. Only one printed map of the Koog von Ritzebüttel , which Rollwagen's father built in 1618, is known.

From 1622 Rollwagen worked as an independent planner and businessman in the Duchy of Gottorf. In August 1622, together with Jacob de Moll, he prepared an expert report on several hydraulic engineering measures for the duke. This included the drainage of the largely unusable Gotteskooges as well as the embankment of the Tielenhemme , for which they set up an extensive cost estimate. With regard to the Gotteskoog, they agreed by contract of September 20, 1622 with the duke that he should receive half of the drained goods. The other half should go to the entrepreneurs and financiers still to be found.

The construction work on the drainage ditches, which are now known as the “Rollwagenzug”, began in 1623. Jacob de Moll had a fatal accident a little later. In June 1624, Rollwagen signed a long-term lease, according to which he should also receive the ducal part of the Gotteskoog. Due to severe flood damage in 1625, he was initially unable to implement the project. On March 31, 1631, he again agreed the maintenance and use of the lands with the duke. In contrast to his father, who only worked as a planning and managerial engineer, Rollwagen's lease was a large company. Due to numerous problems with the drainage of such lands, which were known from similar projects, Rollwagen would probably have only achieved short-term successes.

Rollwagen later traveled to the Netherlands, where he wanted to recruit financiers for the Gotteskoog. During this trip he passed away. His second brother-in-law Isaac de Moll took over his position as dikemaster. Rollwagen's widowed wife lived on the Freesmark farm in Gotteskoog, which the couple had leased with the duke's lands in 1624. During the Burchardi flood , she is "drunk with children, servants and everything else."
