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 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".
After the altercation with Gauguin, Van Gogh returned to his room, where he was assaulted by voices and severed his left ear with a razor (either wholly or in part; accounts differ),[note 9] causing severe bleeding. He bandaged the wound, wrapped the ear in paper, and delivered the package to a woman at a brothel Van Gogh and Gauguin both frequented. Van Gogh was found unconscious the next morning by a policeman and taken to hospital, where Félix Rey, a young doctor still in training, treated him. The ear was delivered to the hospital, but Rey did not attempt to reattach it as too much time had passed.
Theo criticised The Potato Eaters for its dark palette, which he thought unsuitable for a modern style. During Van Gogh's stay in Paris between 1886 and 1887, he tried to master a new, lighter palette. His Portrait of Père Tanguy (1887) shows his success with the brighter palette, and is evidence of an evolving personal style. Charles Blanc's treatise on colour interested him greatly, and led him to work with complementary colours. Van Gogh came to believe that the effect of colour went beyond the descriptive; he said that "colour expresses something in itself". According to Hughes, Van Gogh perceived colour as having a "psychological and moral weight", as exemplified in the garish reds and greens of The Night Cafe, a work he wanted to "express the terrible passions of humanity". Yellow meant the most to him, because it symbolised emotional truth. He used yellow as a symbol for sunlight, life, and God.
In Paris in 1901 a large Van Gogh retrospective was held at the Bernheim-Jeune Gallery, which excited André Derain and Maurice de Vlaminck, and contributed to the emergence of Fauvism. Important group exhibitions took place with the Sonderbund artists in Cologne in 1912, the Armory Show, New York in 1913, and Berlin in 1914. Henk Bremmer was instrumental in teaching and talking about Van Gogh, and introduced Helene Kröller-Müller to Van Gogh's art; she became an avid collector of his work. The early figures in German Expressionism such as Emil Nolde acknowledged a debt to Van Gogh's work. Bremmer assisted Jacob Baart de la Faille, whose catalogue raisonné L'Oeuvre de Vincent van Gogh appeared in 1928.[note 15]
On January 27, 2013, at the age of 87, Van Dyke received the 2013 Screen Actors Guild Life Achievement Award. During his acceptance speech, Van Dyke reminisced about his work over the years as an entertainer and stated that his career has "been full of surprises and a lot of fun." He also praised actors working in the industry today, calling them "the greatest generation of actors" and telling them, "You've all lifted the art to another place now." He continued with a rhetorical question for his Hollywood colleagues: "Aren't we lucky to have found a line of work that doesn't require growing up? I love that." Van Dyke is the 49th recipient of the SAG Life Achievement Award, following 2012 honoree Mary Tyler Moore.
