Peabody died on April 26, 1936, in Manchester, Vermont. Peabody's obituary in
The New York Times stated that he died of a heart attack. A subsequent death listing with funeral information indicated that he died "suddenly, of heart failure." Obituaries in regional newspapers attributed his death to a "heart ailment." ''
Scribner's Magazine'' published an article written by Peabody in its June 1936 issue. The associated author profile stated, "Richard R. Peabody, author of 'The Danger Line of Drink,’ died of a heart attack on April 26, just as this number was going to press.”:383 His wife, Jane McKean, advised Willam Wynne Wister, “He had had a very bad cold and a local doctor came and said that it had developed into pneumonia and that Dick must stay in bed. Well, he gave Dick some medicine and that night Dick died in his sleep.":242 His former wife,
Caresse Crosby, noted, "Dick and I remained devoted friends until the end. I was in Paris when the news of his untimely death reached me.”:92 She did not mention his cause of death. On the other hand, Katherine McCarthy noted, “A common opinion is that Peabody died intoxicated, although the evidence is not conclusive” and that “published sources contradict each other.":60,61 She indicated, "Samuel Crocker, who had once shared an office with Peabody, told Faye R. that he was intoxicated at the time of his death. The personal copy of Peabody’s book belonging to Bill Wilson (one of the founders of A.A.), now in the A.A. Archives, contains the following inscription: ‘Dr. Peabody was as far is known the first authority to state, “once an alcoholic, always an alcoholic,” and he proved it by returning to drinking and dying of alcoholism [...].’ This copy was originally owned by Rosa Burwell of Philadelphia." The principal cause of death was stated to be "acute cardiac dilatation" in the context of "chronic
myocarditis." “Chronic alcoholism” was noted to be a contributing cause. Peabody was survived by Crosby; McKean; his son, William, and daughter, Polly. He is buried in
Harmony Grove Cemetery in Salem, Massachusetts. == Works ==
