An early advocate of bouldering, He was a bit daring and ahead of his time. Eckenstein supported free climbing and bouldering, which were not very common back then. He also liked climbing without paid guides. Some say he organised the first-ever bouldering contests in the Himalayas.
Oscar Johannes Ludwig Eckenstein (9 September 1859 – 8 April 1921) was an English rock climber, mountaineer, and a pioneering figure in the sport of bouldering. Born in London to a German Jewish father and an English mother, he initially trained as a railway engineer and worked for the International Railway Congress Association.
Climbing Career and Innovations
Eckenstein’s passion for mountaineering led him to climb extensively in the English Lake District, North Wales, the Alps, and the Himalayas. He was an early advocate of bouldering, emphasizing the importance of balance and technique over relying solely on guides. In the Lake District, he practiced on the Eckenstein Boulder at Llanberis Pass, where he taught others the art of balance climbing.
In 1902, Eckenstein led the first serious expedition to attempt K2, the second-highest peak in the world. Although the expedition did not reach the summit, it was a significant milestone in high-altitude climbing.
Eckenstein was also an innovator in climbing equipment. He designed the modern crampon, featuring ten points and a hinge between the front and rear frames, which greatly improved traction on ice and snow. Additionally, he shortened the traditional two-handed ice axe, making it more maneuverable and suitable for one-handed use.

Personal Life and Legacy
Eckenstein was known for his eccentric personality and his critical stance toward the Alpine Club, which he felt was elitist. He had a notable friendship with Aleister Crowley, a mystic and magician, who praised Eckenstein’s climbing prowess and strength.
In 1918, Eckenstein married Margery Edwards. He passed away in 1921 from tuberculosis. His contributions to climbing, particularly in bouldering and equipment innovation, have left a lasting impact on the sport.
Eckenstein Boulder
Eckenstein taught others, like Archer Thomson, the art of balance climbing. Because of his love for bouldering, a boulder in Snowdonia was named the Eckenstein Boulder in his honor. This is where he practiced these techniques.
