Thomas Middlemore (1842 – 16 May 1923)[1] was an English mountaineer who made multiple first ascents during the silver age of alpinism. His audacity earned him a reputation as the enfant terrible within the Alpine Club. He was also the head of the Middlemores Saddles leather goods company in Birmingham, England, after the retirement of his father, William Middlemore, in 1881.[2] Thomas Middlemore had taken over the management of the company in 1868 and established a bicycle saddle factory in Coventry.[3]
