GuidoDavid sez, "Len Sassaman, a cryptographer, activist and biopunk died yesterday, he lost the battle against depression in Leuven, Belgium. He is survived by his widow, Meredith L. Patterson, also a hacker and biopunk. His work and actions inspired me and shaped the world we live in, as he was active during the Crypto Wars and

designed and wrote anonymizing tools.

He will be missed, but I hope that his

legacy will go on and I am certain he will continue inspiring our efforts."

An obituary posted on Facebook by Sassaman's friend and fellow hacker Pablos Holman recounted the pair's early work on crypto-systems after they met in 1999. "We were reimagining our world, riddled with cryptosystems that would mathematically enforce the freedoms that we treasured. Anonymous remailers to preserve speech without fear of retribution; onion routers to ensure nobody could censor the internet; digital cash to enable a radically free economy." While much of their work was an academic "geek utopia exercise", Sassaman liked to "get his hands dirty", which led to numerous visits from Federal agencies over remailer abuse, according to Holman: "Len, you are, in fact, an inspiration to those of us who inspired you. You made something great of your life. You left a lot behind for us. Thanks for letting me be a part of it all."
