Past Projects


The Jongerden thatcher family has lived in Eemnes since 1885. A family originating from Gooi that has been in the thatching business since 1800. The oldest details date back to 1650. Reijer was the first thatcher in the family. he must have started his profession about 1800. His trade was passed on to his son Jan Jongerden and grandson Reijer. The latter gave the bussiness to his son Jacob Jongerden. Jacob passed the thatching business on to his two sons Arent and Isaak Jongerden. There were now two thatching businesses in that generation. Isaak passed the business on to his sons Gerrit and Arent Jongerden. There were once again two separate bisinesses in addition to their father's. Isaak sold his firm in the 1960's. Arent started his own business. gerit had a son and handed on his business. Hence Renee Jongerden is the last thatcher from the Jongerden thatching family.
