Daniel Eugene Osman (February 11, 1963 – November 23, 1998) was an American extreme sport practitioner, known for the dangerous sport of free-soloing, rock climbing without ropes or other safety gear.
He 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 lived 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 was also instrumental in the development of the Cave Rock climbing area at Tahoe and many other areas in the Carson City area.
