The southern summit was first climbed by the Swiss mountain guides Christian and Ulrich Almer and their American client, W. A. B. Coolidge from New York. During the 1870s and 1880s, Coolidge claimed a number of first ascents and worked extensively in the Dauphiné Alps. Earlier, the same party had climbed L'Auguille Centrale in 1874. On the summit, they found the cairn built by the Magnin brothers, but ascribed it to a legendary chamois hunter. The day after their ascent of L'Aiguille Meridionale in 1878, Benoît Magnin informed them about his ascent 39 years prior.
