On 27 July 1890, aged 37, Van Gogh shot himself in the chest with a 7mm Lefaucheux à broche revolver.[186][187] There were no witnesses and he died 30 hours after the incident.[160] The shooting may have taken place in the wheat field in which he had been painting, or a local barn.[188] The bullet was deflected by a rib and passed through his chest without doing apparent damage to internal organs – probably stopped by his spine. He was able to walk back to the Auberge Ravoux, where he was attended to by two doctors, but without a surgeon present the bullet could not be removed. The doctors tended to him as best they could, then left him alone in his room, smoking his pipe. The following morning Theo rushed to his brother's side, finding him in good spirits. But within hours Vincent began to fail, suffering from an untreated infection resulting from the wound. He died in the early hours of 29 July. According to Theo, Vincent's last words were: "The sadness will last forever".[189][190][191][192]
There have been numerous debates as to the nature of Van Gogh's illness and its effect on his work, and many retrospective diagnoses have been proposed. The consensus is that Van Gogh had an episodic condition with periods of normal functioning.[195] Perry was the first to suggest bipolar disorder in 1947,[196] and this has been supported by the psychiatrists Hemphill and Blumer.[197][198] Biochemist Wilfred Arnold has countered that the symptoms are more consistent with acute intermittent porphyria, noting that the popular link between bipolar disorder and creativity might be spurious.[195] Temporal lobe epilepsy with bouts of depression has also been suggested.[198] Whatever the diagnosis, his condition was likely worsened by malnutrition, overwork, insomnia and alcohol.[198]
Van Dyke left high school in 1944, his senior year, intending to join the United States Army Air Forces for pilot training during World War II. Denied enlistment several times for being underweight, he was eventually accepted for service as a radio announcer before transferring to the Special Services and entertaining troops in the continental United States.[11] He received his high school diploma in 2004 at the age of 78.[12]
