This obituary is part of a series about people who have died in the coronavirus pandemic.

Dr. Ricardo Castaneda was an avid caricaturist who could often be found at New York Philharmonic concerts or the Metropolitan Opera — in the front row, when possible — scribbling away at sketches of the performers. He illustrated beginner books on psychiatry and addiction. He tried his hand at writing screenplays and composing opera.

For his day job, Dr. Castaneda served as the director of inpatient psychiatry at Bellevue Hospital in Manhattan from 1992 to 2009, before entering private practice as a clinical psychiatrist on the Upper West Side of Manhattan.

Dr. Castaneda died on March 25, shortly after being admitted to Tisch Hospital of N.Y.U. Langone Medical Center in Manhattan. He was 64. His wife, Ana Lucia Fuentes, said the cause was complications of the coronavirus.

Dr. Castaneda was a man of many talents who transferred his faith in human accomplishment to his patients.
