The peak was named by Chester Versteeg and Rudolph Berls on Aug. 14, 1922, when they made the first ascent. '... the true summit was a knife-edge jutting twelve yards to the east. Alternating on one side and then the other of the knife, the last few steps along a narrow ledge on which two people could not have passed, we stopped, not on, but beside, the summit-rock. It stood less than shoulder-high above us. It was impossible to stand on this splinter. We patted it affectionately ...' (Chester Versteeg in SCB 11, no. 4, 1923: 426.)"

"It would occupy more space than is appropriate here to give an account of all the exploring, climbing, and camping trips of the 1890's. Many of them are recorded in the Sierra Club Bulletin, and there were doubtless many others of which no record exists. A few, however, of special interest should be mentioned. Bolton Coit Brown, Professor of Drawing at Stanford University, not only made several notable ascents but added to knowledge of the high country at the head of the Kings and the Kings-Kern Divide by his descriptions, his maps, and his fine sketches. He made the first ascent, solo, of Mount Clarence King in 1896 and the same year joined J. N. LeConte in the first ascent of Mount Gardiner. Professor Brown and his wife Lucy [Lucy Pass on the Kings-Kern Divide is named after her] then crossed the Kings-Kern Divide and climbed Mount Williamson. A little later that summer they returned to the Divide and climbed and named Mount Ericsson, after which Brown ventured out on a northward-jutting knife edge to its highest point, where he built a monument and gave the name 'Mount Stanford.' In 1899 Professor and Mrs. Brown resumed their exploration of the headwaters of the Kings, this time with a third member in their party, their two-year-old daughter. 'We put her on a burro, and wither we went she went also.'"
