Hilda Nilsson (24 May 1876 – 10 August 1917) was a Swedish serial killer from Helsingborg who became known as "the angel maker on Bruks Street".
She is one of Sweden's most notorious female serial killers.
In 1917, she was imprisoned for murdering eight children.
Her trial, which included a mental examination, began on 2 June 1917.
At the conclusion of the trial on 15 June 1917, she was sentenced to death.
She escaped execution punishment by committing suicide while in jail in Landskrona.
She hanged herself with a linen cloth, which she had tied to a cell door, and was thus the last person sentenced to death in Sweden not to have the sentence commuted.
