Elise Adelaïde Haighton (28 May 1841 – 11 August 1911) was a Dutch feminist and free thinker who wrote under the pseudonyms Hroswitha and Brunhilde or Brunehilde.

She was one of the first women in the Netherlands to complete teacher training in accordance with the Dutch Secondary Education Act of 1863.

She initially used two pseudonyms since women were not yet expected to publish literature at that time: Brunhilde (or Brunehilde) and Hroswitha.

She saw the Christian Church, whether Calvinist or Catholic, as an obstacle for women who aspired to intellectual development and autonomy.

In lectures, Haighton opposed the low wages and unhealthy working conditions of factory workers and the legally established iniquity and incapacity of the married woman.
