John Perry Barlow, an internet activist and lyricist for the Grateful Dead, has died.
The digital-rights group Electronic Frontier Foundation said Barlow died in his sleep at home in San Francisco early on Wednesday. He was 70.
Barlow co-founded the EFF in 1990 to champion free expression and privacy online.
In a 1996 manifesto, the "Declaration of the Independence of Cyberspace," he argued that the US and other governments shouldn't impose their sovereignty on the "global social space we are building."
Very sad to hear my friend John Perry Barlow [@JPBarlow] with whom I started the Freedom of Press Foundation has died aged 70. Barlow was a fighter and a lover. He lived a rich life, filled with passion and purpose. The best of America. One such moment: https://t.co/pIL8Fky5Dp— Julian Assange ⌛ (@JulianAssange) February 8, 2018
"He always saw the internet as a fundamental place of freedom, where voices long silenced can find an audience and people can connect with others regardless of physical distance," Cindy Cohn, the EFF's executive director, said in a statement.
Barlow was born in rural Sublette County, Wyoming, in 1947 and grew up in Pinedale, where his parents were ranchers.
He befriended Bob Weir, one of the Grateful Dead's founding members, when they were boarding school classmates at the Fountain Valley School in Colorado. Barlow graduated from Wesleyan University in 1969.
He later returned to Wyoming, where he ran a cattle ranch for nearly two decades and dabbled in Republican politics. He had been battling a variety of debilitating illnesses since 2015, according to supporters who organised a benefit concert for him in October.
Barlow co-wrote several songs for the Grateful Dead with Weir, including "Mexicali Blues," "Black Throated Wind and "Bombs Away".
"John had a way of taking life's most difficult things and framing them as challenges, therefore adventures," Weir said in an online post Wednesday.
"He was to be admired for that, even emulated. He'll live on in the songs we wrote."
His survivors include three daughters and a granddaughter.
Rest in peace, John Perry Barlow. Two years ago, we reflected on his declaration of cyberspace independence and how it evolved since 1996 https://t.co/7aHhxTz96I— WIRED (@WIRED) February 7, 2018
