Elizabeth Webb Nicholls (21 February 1850 – 3 August 1943) was a key suffragist in the campaign for votes for women in South Australia during the 1890s. She took on several high-profile roles in the capital of South Australia, Adelaide and was President of the Woman's Christian Temperance Union (WCTU) of South Australia, one of the most prominent organisations in the successful campaigns which made South Australia the first of the Australian colonies to grant women the right to vote in 1894.[1][2]
