Daniel Eugene Osman (February 11, 1963 – November 23, 1998) was a Japanese-American extreme sport practitioner, known for the dangerous sports of free-soloing, rock climbing without ropes or other safety gear.
Dan 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.
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).
