Holdsworth, (25 February 1899 – 20 June 1976) was an English scholar, academic, educationalist, cricketer and a distinguished Himalayan mountaineer.
He was a member of the first expedition to Kamet in 1931, which included other stalwarts such as Eric Shipton and Frank Smythe.
Holdsworth, along with Shipton and Smythe, are credited with the discovery of the Valley of Flowers, now a UNESCO World Heritage Site, during their return from Kamet.
