Heather Marsh is a renowned philosopher, programmer, and human rights activist. She is widely recognized for her work in shaping and accelerating international events such as the 2011 15-M movement in Spain and the ensuing global Occupy Movement. Her profound insights into power dynamics and organizational strategies have significantly contributed to the transformation of the Anonymous collective into a global activist movement.

Heather's significant contributions extend to the early stages of Wikileaks, where she played a pivotal role by directing the focus of the organization's supporters towards critical human rights issues. Her departure from Wikileaks was in early 2012.

Heather is the sole individual to have been instrumental in the formation of three of the most influential movements of the last decade: Anonymous, Occupy, and Wikileaks.
