(CNN) -- Aaron Swartz, an Internet savant who at a young age shaped the online era by co-developing RSS and Reddit and later became a digital activist, has committed suicide.
Swartz's body was found Friday evening in Brooklyn, said Ellen Borakove, a spokeswoman with the New York medical examiner's office. The 26-year-old had hanged himself in his apartment.
His family and partner said they were "in shock, and have not yet come to terms with his passing."
"Aaron's insatiable curiosity, creativity, and brilliance; his reflexive empathy and capacity for selfless, boundless love; his refusal to accept injustice as inevitable -- these gifts made the world, and our lives, far brighter," they said in a statement. "We're grateful for our time with him, to those who loved him and stood with him, and to all of those who continue his work for a better world."
