Daniel Eugene Osman (February 11, 1963 – November 23, 1998)[1] was a Japanese-American extreme sport practitioner, known for the dangerous sports of free-soloing, rock climbing without ropes or other safety gear. He also participated in rope free-flying or rope jumping, falling several hundred feet from a cliff then being caught by a safety rope, for which his record was over 1,000 feet (300 m). He was known for living a bohemian lifestyle, working as a part-time carpenter and living in Lake Tahoe, California. He was the subject of several rock climbing videos, which brought free-soloing to a wider audience. Dan had one daughter, Emma Osman.[2]

Climbing films[edit]

Osman appeared in Eric Perlman's Masters of Stone series, free soloing Atlantis (5.11+) on The Sorcerer in The Needles in the Sequoia National Forest. Plus Airy Interlude (5.10b, then 5.9) on The Witch, also in Needles (in California's Sierras). He also is featured crashing a BMX bicycle, ziplining off The Witch, taking a 192 feet (59 m) whipper for fun in Yosemite, and on-sight free-soloing Bolder Display of Power (5.11).


Dan Osman died on November 23, 1998 at the age of 35 after his rope failed while performing a "controlled free-fall" jump from the Leaning Tower rock formation in Yosemite National Park. Osman had come back to Yosemite to dismantle the jump tower but apparently decided to make several jumps (over a few days) before doing so.[2] The failure was investigated by the National Park Service with assistance from Chris Harmston, Quality Assurance Manager at Black Diamond Equipment. Harmston concluded that a change in jump site angle probably caused the ropes to cross and entangle, leading to the rope cutting by melting.[3] Miles Daisher, who was with Osman when he made the jump, stated that the ropes used in his fatal jump had been exposed to inclement weather — including rain and snow — for more than a month before the fatal jump, but that the same ropes were used for several shorter jumps on the previous and same day.[2]
