Troccoli's involvement in artillery camouflage in WWI

Giovanni Battista Troccoli (1882-1940) was an Italian-American painter who came to the US at age 11 in 1893. He began his career in Boston, where he worked as a wood carver at age 14, and soon after as a modeler for a well-known Boston sculptor, Hugh Cairns.

He turned from sculpture to painting, and in the process studied with Denman Ross (author of A Theory of Pure Design: Harmony, Balance, Rhythm), and with artist and frame designer Hermann Dudley Murphy, both of whom were associated with Harvard University. The latter, as explained in earlier posts, supervised the application of ship camouflage during World War I.

Troccoli also studied painting in Paris, Amsterdam and Spain, and seems to have been primarily known as a portrait painter. Of greater interest at the moment is his little-known involvement in wartime camouflage. During WWI, perhaps as a civilian, he was involved in developing camouflage patterns for American field artillery at the Watertown Arsenal, in Watertown MA. It is unconfirmed but he may have contributed to the camouflage of the field guns that are shown above and below in this post, all of which were apparently processed at Watertown.
