This altitude record, though not the summit record, was broken a few months later, on 20 October 1907, when the Norwegians Carl Wilhelm Rubenson and Ingvald Monrad Aas came within 50 m of ascending the 7338 m east summit of Kabru. It is noteworthy that Carl Rubenson afterwards believed that Graham, Boss and Kaufmann had ascended that summit 24 years before.
