Elze van den Ban

Elizabeth Frederika van den Ban, known as Elze, (18 October 1894 - 25 December 1973) was a Dutch urban planner and chief engineer of the Rijkswaterstaat (Department of Public Works) at Zuiderzee Works where she introduced curvatures rather than straight lines into the urban planning process of polders and dikes.

Early life and education
Elizabeth Frederika van den Ban, known as Elze, was born in Haarlem on 18 October 1894 to Anna Kater and Jacob van den Ban. Her father was an architect who worked in and around in Haarlem and Amsterdam. She was one of three sisters, Anna Jacoba (Ans) Meerdink-van den Ban (b,1899) who became a pastor in Soest and Frederika Elisabeth Hugenholtz-van den Ban (b. 1896). Their mother - Anna Kater - died young in 1911. Age 16, van den Ban told her mother that she wanted to study at Delft University of Technology and she became the first woman from the Netherlands to graduate as a civil engineer there.

Career
Van den Ban briefly taught mathematics at the Municipal hogere burgerschool (secondary school) in Haarlem in 1919. After graduating from university, she joined her father Jacob van den Ban at his architectural firm. She then held a position with Provincial Water Authority of North Holland as an urban planner for almost a quarter of a century. She was often referred to as E. F. van den Ban professionally. In 1949, Van den Ban was assigned to the Zuiderzee Works Department as an urban planner. Here, she revolutionised the development of planning by promoting the use of curvatures in the construction of streets and roads, rather than straight lines  and was involved in the creation of the Zuid-Kennemerland National Park initially suggested by Jac. P. Thijsse.
