(March 29, 1862 - July 6, 1947) was a Swiss-born American portrait painter and impressionistic painter of roses and still life.
He was born Felice Adolfo Meller on March 29, 1862 at Airolo, in the Ticino in Switzerland, into a prominent patrician family whose lineage descended from Alfred the Great, Charlemagne and Doge Pietro Orseolo of Venice, through the von Rechburg family (a lady from which family married a Meller) and by the 18th and 19th centuries included mercenaries, lawyers, hoteliers and businessmen. His father was lawyer Carl Alois Meller (1825 - 1887), Gerichtspräsident (Presiding Judge) of the Cantonal Courts, and his mother Genovefa Lombardi (1836 - 1920), daughter of Felice Lombardi who was Director of the Hospice on the St Gotthard Pass, which he took over from the Capuchin monks who had run this for centuries. Adolfo was their sixth of nineteen children, most of whom survived infancy. The family spoke Airolese mainly, a local dialect of Ticinese Italian, as well as Swiss-German. His family were Roman Catholic.
