When he travelled to Paris in 1896, he joined the Colarossi’s studio and trained under Whistler eventually becoming his massier or head student.

The Times said that Cuneo had a fine physique and was a notable athlete, and as a boxer was famous not only on the Pacific slope, but also in Paris and in London.
