|Known for||Environmentalist, Gullfoss|
Sigríður Tómasdóttir (1874 - 1957) was an Icelandic environmentalist whose activism helped preserve Gullfoss waterfalls, protecting it from industrialization. She is widely seen as Iceland's first environmentalist and is memorialized on a sculpture near Gullfoss.
Tómasdóttir was born in Brattholt in 1874 and grew up on her family's sheep farm. She did not receive any official education but was well read and artistic. She and her sisters would act as guides for visitors of the waterfalls.
In 1907, landowners including Tómasdóttir's father, Tómas Tómasson, a signed a deal to allow the construction of a hydroelectric dam across the Hvítá River that would result in the submergence of Gulfoss. Upset by the deal, Tómasdóttir took legal action against the development and staged several protests. She made numerous treks of 120 kilometers to Reykjavík, by some accounts on foot, to meet with government officials and later threatened to throw herself in the waterfalls.
She was represented legally by Sveinn Björnsson, who later became Iceland's first president. Tómasdóttir's efforts ultimately failed with the legal system but gained positive public attention. The lease contracts later were canceled and the hydroelectric project was never constructed. Gulfoss and the surrounding area was eventually sold to the Icelandic government and was made a permanent conservation site in 1979.
