Louise Kaiser (Medemblik, 15 October 1891 – Bussum, 2 April 1973) was a Dutch phonetician and linguist and the first female lecturer at the University of Amsterdam and became known for her research into the phonetic and physical-anthropological measurements on the people of Urk in the Netherlands.

[1] Kaiser gave her first courses in applied phonetics in the physiological laboratory of the University of Amsterdam as early as 1922.

Her research mainly focused on the former Zuiderzee area, including the island of Urk, and the newly drained polders.

There has long been scientific interest in the ancient communities in the Zuiderzee area, due to its isolated location and the supposed original population.

As the niece of the Dutch artist Johann Wilhelm Kaiser, she had become interested in the visual arts at an early age.

[5] According to Meertens, "For though anyone who knew her knows she was a strong-willed woman who was not afraid to take on any adversary, she was fundamentally averse to putting herself in the limelight."
