John Gill is one of the pioneers of bouldering, putting up many hard first ascents in the US at a time when bouldering was not understood as an activity in its own right. With a background in gymnastics, Gill applied a similar mentality to rock climbing, transferring some of the training ideas and using gymnastic chalk. For Gill, as in gymnastics, elegance of execution was as important as difficulty. This did not stop him from establishing many extraordinarily hard problems however, and for decades his problems were amongst the hardest in the world. When he applied his skills to taller routes, Gill also excelled. His route The Thimble, climbed solo and ground up in 1961 and considered around 7A+, was well ahead of its time. After attempting to repeat the line, Royal Robbins said of it:

Inventor of the hueco V grading scale. The V comes from his nickname "Verm". He was prolific in the early development of bouldering in the US, taking over the mantle from John Gill and extensively developing Hueco Tanks during the 1980s and 1990s, with over 400 problems to his name.
