Lived with Michelle Triola from 1976 until her death in 2009. Van Dyke had become friendly with her before his marriage ended and in his autobiography he admits that the final cause of his divorce from his wife was when he gave Michelle Triola out of his own pocket the six-figure amount she had sued for unsuccessfully in her infamous "palimony" case against Lee Marvin.
The exact sequence of events which led to Van Gogh's mutilation of his ear is not known. Gauguin stated, fifteen years later, that the night followed several instances of physically threatening behaviour. Their relationship was complex, and Theo may have owed money to Gauguin, who was suspicious that the brothers were exploiting him financially. It seems likely that Van Gogh had realised that Gauguin was planning to leave. The following days saw heavy rain, leading to the two men being shut in the Yellow House. Gauguin reported that Van Gogh followed when Gauguin left the house for a walk, and "rushed towards me, an open razor in his hand". This account is uncorroborated; Gauguin was almost certainly absent from the Yellow House that night, most likely in a hotel.
Van Gogh entered the Saint-Paul-de-Mausole asylum on 8 May 1889, accompanied by his carer, Frédéric Salles, a Protestant clergyman. Saint-Paul was a former monastery in Saint-Rémy, located less than 30 kilometres (19 mi) from Arles, and was run by a former naval doctor, Théophile Peyron. Van Gogh had two cells with barred windows, one of which he used as a studio. The clinic and its garden became the main subjects of his paintings. He made several studies of the hospital's interiors, such as Vestibule of the Asylum and Saint-Rémy (September 1889). Some of his works from this time are characterised by swirls, such as The Starry Night. He was allowed short supervised walks, during which time he painted cypresses and olive trees, including Olive Trees with the Alpilles in the Background 1889, Cypresses 1889, Cornfield with Cypresses (1889), Country road in Provence by Night (1890). In September 1889 he produced two further versions of Bedroom in Arles.
The adult Broadway cast (Dick, Paul Lynde, Maureen Stapleton) who recreated their roles for the film version of Bye Bye Birdie (1963) were generally disappointed in the film. It was felt that director George Sidney placed far too much focus on Ann-Margret's teen role, a role that was secondary in the stage hit. Ann-Margret was at the time experiencing a meteoric rise in films.
Van Gogh painted several landscapes with flowers, including roses, lilacs, irises, and sunflowers. Some reflect his interests in the language of colour, and also in Japanese ukiyo-e. There are two series of dying sunflowers. The first was painted in Paris in 1887 and shows flowers lying on the ground. The second set was completed a year later in Arles, and is of bouquets in a vase positioned in early morning light. Both are built from thickly layered paintwork, which, according to the London National Gallery, evoke the "texture of the seed-heads".
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. He received his high school diploma in 2004 at the age of 78.
