Marie Harding, widely known as “Flash,” is a founding member of the Institute of Ecotechnics and
one of the central figures in the history and development of Synergia Ranch. Together with John Allen,
she co-founded Synergia Ranch LLC in 1969 and has dedicated more than five decades to the growth,
continuity, and stewardship of the Institute’s projects and communities.
Over the course of her career, Marie has served in numerous roles including director, financial officer,
builder, organizer, and operational manager. Most recently, she retired from her formal position as
General Manager and Director of Operations at Synergia Ranch after more than fifty-five years of
continuous service. Her work helped shape the ranch into an internationally recognized center for
ecological experimentation, interdisciplinary dialogue, and long-term collaborative living.
Marie also played a pioneering role in the creation of the RV Heraclitus, serving both as a builder and
as the vessel’s first captain. The Heraclitus became one of the Institute’s most ambitious and
enduring projects, undertaking global expeditions focused on ecological systems, oceans, culture,
and human adaptation.
Known for her practical intelligence, perseverance, and deep institutional memory, Marie carried
much of the operational and organizational continuity that sustained Synergia Ranch and related
projects across generations. Her contribution extends beyond administration into the physical and
cultural fabric of the ranch itself.
Alongside her ecological and organizational work, Marie has maintained a lifelong parallel practice
as a painter since the 1960s. Her work has been exhibited in a variety of settings, and she created
several major mural projects for the Caravan of Dreams, including murals on the History of Jazz and
Blues, Planetary Dances, and theatrical productions presented at the venue. Her paintings remain
an integral part of the visual atmosphere of Synergia Ranch, where original works are displayed
throughout the Retreat Center and residences.
Although retired from formal management, Marie continues to live at Synergia Ranch and remains an
important elder presence within the community, offering historical perspective, guidance, and
counsel to younger generations carrying the work forward.
