Van Dyke had four children with his first wife, Margie. The pair lived separate lives for years, before officially divorcing in 1984. The actor became involved with Michelle Triola, an ex-girlfriend of Lee Marvin, in the late 1970s. Trioia had been working as Van Dyke's agent's secretary when they first met. Van Dyke stayed with Triola for nearly 30 years, until her death in 2009. In March 2012, the 86-year-old actor wed 40-year-old makeup artist Arlene Silver.
Van Gogh suffered from psychotic episodes and delusions and though he worried about his mental stability, he often neglected his physical health, did not eat properly and drank heavily. His friendship with Gauguin ended after a confrontation with a razor when, in a rage, he severed part of his own left ear. He spent time in psychiatric hospitals, including a period at Saint-Rémy. After he discharged himself and moved to the Auberge Ravoux in Auvers-sur-Oise near Paris, he came under the care of the homeopathic doctor Paul Gachet. His depression continued and on 27 July 1890, Van Gogh shot himself in the chest with a revolver. He died from his injuries two days later.
Van Gogh was unsuccessful during his lifetime, and was considered a madman and a failure. He became famous after his suicide, and exists in the public imagination as the quintessential misunderstood genius, the artist "where discourses on madness and creativity converge". His reputation began to grow in the early 20th century as elements of his painting style came to be incorporated by the Fauves and German Expressionists. He attained widespread critical, commercial and popular success over the ensuing decades, and is remembered as an important but tragic painter, whose troubled personality typifies the romantic ideal of the tortured artist. Today, Van Gogh's works are among the world's most expensive paintings to have ever sold at auction, and his legacy is honoured by a museum in his name, the Van Gogh Museum in Amsterdam, which holds the world's largest collection of his paintings and drawings.
His film work affected his TV career: the reviews he received for his role as D.A. Fletcher in Dick Tracy led him to star as the character Dr. Mark Sloan first in an episode of Jake and the Fatman, then in a series of TV movies on CBS that became the foundation for his popular television drama Diagnosis: Murder. The series ran from 1993 to 2001 with son Barry Van Dyke co-starring in the role of Dr. Sloan's son Lieutenant Detective Steve Sloan. Also starring on the same show was daytime soap actress Victoria Rowell as Dr. Sloan's pathologist/medical partner, Dr. Amanda Bentley, and Charlie Schlatter in the role of Dr. Sloan's student, Dr. Jesse Travis. Van Dyke continued to find television work after the show ended, including a dramatically and critically successful performance of The Gin Game, produced for television in 2003 that reunited him with Mary Tyler Moore. In 2003, he portrayed a doctor on Scrubs. A 2004 special of The Dick Van Dyke Show titled The Dick Van Dyke Show Revisited was heavily promoted as the first new episode of the classic series to be shown in 38 years. Van Dyke and his surviving cast members recreated their roles; although nominated for a Primetime Emmy,[better source needed] the program was roundly panned by critics. In 2006 he guest-starred as college professor Dr. Jonathan Maxwell for a series of Murder 101 mystery films on the Hallmark Channel.
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. Perry was the first to suggest bipolar disorder in 1947, and this has been supported by the psychiatrists Hemphill and Blumer. 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. Temporal lobe epilepsy with bouts of depression has also been suggested. Whatever the diagnosis, his condition was likely worsened by malnutrition, overwork, insomnia and alcohol.
I've found a home here because actors have always said, 'He's really a dancer', and dancers said, 'No, no he's a singer', and singers said, 'No I think he's an actor.' I don't know, I was never that good at anything but I did a little bit of it all. I've never studied dancing but I've always loved to dance. I never sang anywhere except the shower and it took me forever to get into the high school choir. When I auditioned for Bye Bye Birdie (1963) I did a song and a little soft-shoe and for some reason they saw I could move. And I've never studied acting - which is maybe lucky otherwise I'd just be a copy of everybody else.
