Cuneo began his studies in art while still living in San Francisco, at the
Mark Hopkins Art Institute. When he travelled to Paris in 1896, he joined the Colarossi's studio and trained under
Whistler eventually becoming his
massier or head student. Cuneo set up an afternoon sketching school with
Edith Œnone Somerville (1858–1949). Teaching sketching and boxing helped Cuneo to support himself in Paris.
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. Cuneo was living at 9, Rue Campagne, Première Montparnasse, Paris, in 1900 when he first exhibited at the
Royal Academy. He showed two works in that year, both of them illustrations from
King Lear by
Shakespeare. Cunoe also exhibited at other venues. ==Move to London==
