The second ascent, in 1862, was made by Leslie Stephen.
Starting with Melchior Anderegg and Franz Biener, of Zermatt.
It was from a chalet below the Schallenberg Alp, nearly 2 hours lower than Tyndall's bivouac, that Stephen gained the highest point in 9.5 hours, and returned to Randa in 7.5 hours more, reaching Zermatt the same evening.

In 1877, another route was opened by W. E. Davidson, J. W. Hartley and H. S. Hoare, with guides P. Rubi, J. Juan and A. Pollinger.
After climbing part of the lower south-east face above the Schali Glacier, they reached the Schaligrat (south-west ridge) and continued to the summit.
The complete ridge (which was considered too difficult and dangerous in its lower part) was first climbed in 1895 by J. M. Biner, A. Imboden and E. Broome.
The south-east face was completely climbed in 1906 by Geoffrey Winthrop Young and R.G. Mayor with the guide Josef Knubel of St. Niklaus in the canton Valais.

The glaciated north-east face was first climbed in 1871 by J. H. Kitson with guides Christian Almer and his son.
Almer wanted to reach the summit by nine o'clock in the morning while Kitson's wife watched them from the Gornergrat.
In fact the difficulties were more serious than expected and they didn't reach the summit before midday.
Shortly after, the ascent was repeated by W. A. B. Coolidge and Meta Brevoort.
Both expeditions climbed the part of the face below the Grand Gendarme and continued near the north ridge.
In 1909 G. W. Young and J. Knubel climbed the face by the central spur.

The west face was first climbed in 1879 by G. A. Passingham with guides F. Imseng and L. Zurbrücken.
Other routes on the face were opened in 1883 and 1889.
The easiest passage on the east face was found in 1890 by G. W. Young, who climbed the spur under the Grand Gendarme with L. and B. Theytaz by a route known as the Younggrat.

The summit of the Grand Gendarme on the unexplored north ridge was first reached in 1898.
One month later, on 21 September 1898, H. Biehly and H. Burgener made the first complete traverse on the north ridge to the summit from the Bishorn.

In 1888 George Winkler was killed in a fall on the west face.
He left Zinal alone on 17 August, without telling others his precise route.
The rescue team only found a photo and a hat near an avalanche cone.
His body was not found until the summer of 1956, on the Weisshorn Glacier.
John Garforth Cockin was also killed making a solo attempt on the south-east face twelve years later.

In 1925 Eleonore Noll-Hasenclever, H. Pfann and H. Trier were caught in an avalanche on the north-east face when they tried to reach the east ridge after interrupting their ascent on the north ridge on account of adverse weather conditions.
Pfann and Trier survived, but Hasenclever died from asphyxiation.
