A 1926 fire station design competition revealed the unexpected talent of Jakoba Mulder, as her anonymous entry drew praise for its masculine toughness before judges discovered the creator was a woman. This early triumph set the trajectory for a career that reshaped Amsterdam through large-scale urban planning, public park design, and the integration of children's play areas into metropolitan infrastructure.
Academic Foundation and Early Career
Born in Breda in 1900 to infantry officer Hendrik Mulder and Sara Maria Boon, she spent her youth in Semarang, Dutch East Indies, before returning to the Netherlands at age 13. By 18, she enrolled in the architecture program at the Delft University of Technology. She graduated in 1926 as a construction engineer, becoming the first woman to finish the urban design program. Following her success in the fire station competition, the municipality of Delft hired her as a deputy architect to work on town expansion projects.
Leading Amsterdam Urban Development
Mulder joined the Amsterdam urban development department in 1930 as an assistant, supervising a team of 30 male artists under the direction of Theodoor K. van Lohuizen and Cornelis van Eesteren. Her professional influence grew significantly until she was named chief architect of Amsterdam in 1952. In 1958, she succeeded van Eesteren as the head of the city's urban development department, a role she held until her retirement in 1965.

Her most expansive project was the Amsterdamse Bos, a 200-acre park she managed from 1935 until its completion in 1970. She oversaw a diverse team of experts in fields ranging from soil science to public health, earning the nickname Miss of the Bos. Between 1936 and 1939, she also designed Beatrix Park, named for Princess Beatrix. In 2018, the city installed a monument in the park titled Future Past Glory to honor her contributions.
Post-War Reconstruction and Playgrounds
During the post-World War II reconstruction of Amsterdam, Mulder collaborated with architect Aldo van Eyck to create more than 700 play spaces. She developed a system of interlocking L-shaped residential blocks to improve light and variety in housing, placing playgrounds in courtyards visible from kitchens. One notable example of her functional design, the Gibraltar Street wading pool, remains in operation during the summer months.
Teaching and Retirement
Mulder never married and continued her professional engagement after leaving the city administration. From 1966 to 1970, she served as a professor of planning at the University of Amsterdam. Throughout her academic career, she actively encouraged young women to enter the design professions, characterizing urban planning as a field highly suitable for women. She was recognized as a member of the Order of Orange-Nassau and died in Breda in 1988.
