Ruth Tringham

Ruth Tringham

Librarian and Board Secretary

By training and profession Ruth is an archaeologist. She has investigated very early farmers (all long dead) all over Eastern Europe and, most recently, in Turkey. She came to the US from England as part of the so-called “brain drain” and, after an East Coast sojourn, ended up very happily in California teaching at UC Berkeley. Ever since the technology was available, she has been incorporating digital audio-visual media into her research. After retiring from teaching a few years ago, she founded with some colleagues a non-profit company, the Center for Digital Archaeology. Music has always been in her life. She played violin from the age of 9 until college. She gave up the violin and took up the guitar, playing folk songs at excavations wherever she landed up, improvising to match the local rhythms and melodies. She didn’t get into choral singing until she came to the US, but has continued to do that as a passionate part of her life. More at http://ruthtringham.com/

Jess Hobbs

Jess Hobbs

Art Department

People have often described Jessica Hobbs as someone trying to lead a compulsively artistic life, which is more or less true. She started off her adventure in a small Sierra Foothill town and eventually meandered her way to the San Francisco Bay Area. Along the way Jess has worn many hats; running and creating community art programs, counseling teenagers, curating, exhibiting, designing, photographing, running a power company, and playing with some girls who love lipstick and accelerants. She is an MFA graduate from the San Francisco Art Institute and believes collaboration is key in community and art. This can be seen through the work of her non-profit the FLUX Foundation and her open-source alternative energy company All Power Labs.
