Tommy Caldwell (born August 11, 1978) is an American rock climber. He is accomplished in several types of climbing, including sport climbing, hard traditional climbing, big-wall speed climbing and big-wall free climbing. He made the first ascents (FA) of some of the United States' hardest sport routes (as of 2008) including Kryptonite (5.14c/d) and Flex Luthor (5.15a) at the Fortress of Solitude, Colorado. In January 2015, Caldwell and Kevin Jorgeson completed the first-ever free climb of the Dawn Wall of El Capitan in Yosemite National Park. It was documented by photos and journalistically by Tom Evans (see El Capitan).
Caldwell is a big-wall climber, with the first free ascents (FFA) of a handful of El Capitan routes to his credit. In May, 2004 he completed the first free ascent of Dihedral Wall. In 2005, he and Beth Rodden (swapping leads) made the third and fourth free ascents of The Nose. Two days later, on October 16, Caldwell free-climbed The Nose in less than 12 hours. A few days later, Caldwell climbed The Nose in 11 hours, descended the East Ledges, and then climbed Freerider, topping out 12 hours later – the first ascent of two El Capitan free climbs in 24 hours. On El Capitan, Caldwell has also free-climbed: Lurking Fear, Muir Wall (Cosgrove var. to Magic Mushroom finish, FFA), West Buttress, Salathé, Zodiac and Magic Mushroom.
