Jan Willem Tellegen

Jan Willem Cornelis Tellegen (May 13, 1859 in Groningen – April 16, 1921 in Amsterdam) was mayor of Amsterdam from 1915 to 1921. Tellegen trained as a technical and civil engineer. He was director of public works in Arnhem before becoming director of building and housing in Amsterdam, where, around 1905, he brought in building regulations to enforce the 1902 Housing Act. Though developers and architects complained the measures were too restrictive, they were very effective in producing "people's homes".
