She was one of the first "progressive activists" to tie to the suffragette movement to the labor movement, thereby achieving mutual goals of emancipation of both women and workers.

Shoulder to Shoulder is a 1974 BBC television serial and book relating the history of the women's suffrage movement, both edited by Midge Mackenzie.  The drama series grew out of discussions between Mackenzie and the actress and singer Georgia Brown, who was dissatisfied at the lack of decent roles for women in TV drama.  Brown enlisted the producer Verity Lambert in the project she and Mackenzie were devising to dramatise the struggle for women's suffrage, and the three women presented the idea to the BBC, which gave approval for the series.  Originally they had hoped to use only female script writers but this proved impracticable.  Male writers were used and the three female originators of the project found they needed to remove from their scripts a number of 'innuendoes, misconceptions and untruths' indicative of what Georgia Brown termed "the male point of view".
Answer: Sylvia Pankhurst
