Oliver Wendell Holmes died, aged 85, on October 7, 1894.
You have cited the father of Justice Holmes, who was a physician and professor of medicine at Harvard.
Justice Oliver Wendell Holmes, Jr. (1841-1935)
Oliver Wendell Holmes, Jr. would serve on the Supreme Court longer than any other person-thirty years. He was called "The Great Dissenter" because he was often at odds with his fellow justices and was capable of eloquently expressing his dissents. Louis Brandeis often joined him in dissents, and their views often became the majority opinion in a few years' time. Holmes resigned due to ill health in 1932, at age ninety. He died in 1935 [just months short of his 94th birthday] and is buried in Arlington National Cemetery next to his wife.
There are two Oliver Wendell Holmses. The one on the Supreme Court was still around after World War I. The poet-father-doctor must be the one who died in 1894.
