I know Van Gogh met the impressionists. A lot of other people met the impressionists. Also, the impressionist moment as art historians conceive of it was largely over by 1887.
But I don't think most art historians place Van Gogh's art firmly in the impressionist moment. I don't think he even ever showcased his work in the annual impressionist art shows in Paris. His most famous works tend to be considered post-impressionist.
