Peter Bohren (20 June 1822 – 4 July 1882) was a Swiss mountain guide from Grindelwald.
Peter Bohren made three first ascents in the Bernese Alps. On 11 August 1858 he jointly made the first ascent of the Eiger (3967 m above sea level), climbing via the west face with fellow guide, Christian Almer, and Charles Barrington. The group started at 3:30 a.m at the Hotel Wengernalp and the mountaineers reached the summit of the Eiger in the fog at 12 noon.[1]
The following year, he reached the Aletschhorn (4193 m) with two colleagues and a guest on 18 June 1859. His last first ascent was the Äbeni Flue (3962 m) together with a colleague and a guest via today's normal route (southwest flank and southeast ridge) on 27 August 1868.[2]
