Arthur C. Clarke, a visionary science fiction writer who won worldwide acclaim with more than 100 books on space, science and the future, died Wednesday in his adopted home of Sri Lanka, an aide said. He was 90.
Clarke, who had battled debilitating post-polio syndrome since the 1960s and sometimes used a wheelchair, died at 1:30 a.m. after suffering breathing problems.
Clarke moved to Sri Lanka in 1956, lured by his interest in marine diving which he said was as close as he could get to the weightless feeling of space.
"I'm perfectly operational underwater," he once said.
Co-author with Stanley Kubrick of Kubrick's film "2001: A Space Odyssey," Clarke was regarded as far more than a science fiction writer.
He was credited with the concept of communications satellites in 1945, decades before they became a reality. Geosynchronous orbits, which keep satellites in a fixed position relative to the ground, are called Clarke orbits.
He joined American broadcaster Walter Cronkite as commentator on the U.S. Apollo moonshots in the late 1960s.
