Dr. Nolan D. C. Lewis, 90, a psychiatric consultant to the Nuremberg war crimes trials who declared that 22 top Nazis were "sane and fit for trial," died of congestive heart failure Tuesday at Frederick Memorial Hospital in Maryland.

A psychoanalyst who specialized in schizophrenia, Dr. Lewis interviewed and evaluated the Nazis being brought to trial after World War II.

Those he examined included Rudolf Hess, Hitler's deputy and the man who made an unauthorized and hapless flight to Britain with peace overtures early in the war; Reichsmarschall Hermann Goering, head of the German air force during the war; Albert Speer, minister of armaments and war production toward the end of the war; field marshal Wilhelm Keitel, head of the German combined general staff during the war, and Joachim von Ribbentrop, Nazi foreign minister during the war.

Dr. Lewis was fluent in German and had studied under Sigmund Freud at the University of Vienna. He was professor of psychiatry and chief of the department of psychiatry at Columbia University in New York City when he was asked to examine the Nazi leaders.

Before going to Columbia Niversity, he had been director of clinical psychiatry at St. Elizabeths Hospital here and a professor of clinical psychology at George Washington University from 1925 until 1936.

From 1953 to 1958, he directed research in neurology and psychology for New Jersey hospitals and agencies.

Dr. Lewis wrote 225 papers in his fields and contributed numerous articles to scientific and medical journals.

He was born in Coudersport, Pa., and graduated from the University of Maryland. From 1914 to 1918, he was a fellow in psychology at Johns Hopkins University.

Dr. Lewis, who lived in Strawsleigh, Md., was a member of numerous professional associations. He received the first Emil Gutheil medal from the Association for the Advancement of Psychotherapy and was honored by the American College of Psychoanalysts for his achievements in psychiatry.

His wife of 59 years, the former Anna Horn, died in March.

Survivors include a daughter, Mary Anne, of Strawsleigh, and a son, Nolan Jr., of Valhalla, N.Y.
