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.
During the last six or seven months of the year 1889, he has also created at least fifteen paintings of olive trees, a subject which he considered as demanding and compelling. Among these works are Olive Trees with the Alpilles in the Background (1889), about which in a letter to his brother Van Gogh wrote, "At last I have a landscape with olives".While in Saint-Rémy, Van Gogh spent time outside the asylum, where he painted trees in the olive groves. In these works natural life is rendered as gnarled and arthritic as if a personification of the natural world, which are, according to Hughes, filled with "a continuous field of energy of which nature is a manifestation".
In despair of ever being able to overcome his loneliness or be cured, van Gogh shot himself. He did not die immediately. When found wounded in his bed, he allegedly said, “I shot myself.…I only hope I haven’t botched it.” That evening, when interrogated by the police, van Gogh refused to answer questions, saying, “What I have done is nobody else’s business. I am free to do what I like with my own body.”
Van Gogh had a catastrophic love life. He was attracted to women in trouble, thinking he could help them. When he fell in love with his recently widowed cousin, Kate, she was repulsed and fled to her home in Amsterdam. Van Gogh then moved to The Hague and fell in love with Clasina Maria Hoornik, an alcoholic prostitute. She became his companion, mistress and model.
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.
