John Nuttall was a prominent figure in British mountaineering during the mid20th century, renowned for his pioneering climbs and contributions to fellwalking. Born in 1933, Nuttall developed a passion for the outdoors early in life, exploring the rugged landscapes of the English Lake District. He distinguished himself as a skilled and daring climber, tackling challenging routes with minimal equipment. His climbing exploits extended beyond the UK, encompassing expeditions to the Alps and other mountainous regions.

However, Nuttall is perhaps best known for his meticulous and systematic approach to fellwalking. He meticulously documented the fells of England, meticulously recording their heights and locations. This dedication culminated in the publication of "The Mountains of England and Wales" in 1958, a comprehensive guide that listed every summit over 2,000 feet in England and Wales with a prominence of at least 15 meters. This work established the "Nuttall" list, which became a popular objective for fellwalkers aiming to summit all the qualifying peaks.

Nuttall's contribution wasn't limited to creating the list; he himself completed the round multiple times, demonstrating his deep understanding and appreciation for the British landscape. His meticulous approach and detailed records inspired a generation of fellwalkers and contributed significantly to the growing popularity of the sport. Beyond his climbing and fellwalking achievements, Nuttall was also known for his independent spirit and his commitment to preserving the natural environment. He remained an active figure in the outdoor community throughout his life, sharing his knowledge and inspiring others to explore the mountains responsibly. He passed away in 2014, leaving behind a lasting legacy as a pioneer of British mountaineering and a champion of fellwalking.
