Alan Turner, who drew on Surrealism and Abstract Expressionism in acclaimed paintings and drawings that could be humorous, disturbing or poignant, died Feb. 8 at his loft in Lower Manhattan. He was 76.

Mr. Turner’s art was widely exhibited and wide ranging. In the late 1970s, he produced mesmerizing paintings of trees. Then came works featuring humanoid figures and faces, with body parts distorted or bizarrely placed. In recent years, spurred by cardboard shelters in the homeless encampments along the Tiber River that he saw on his frequent trips to Rome, he developed a series, mostly in graphite, that explored boxes that harbor people, pets or even memories.

In an interview with Dan Nadel, who curated a Parker Gallery show of his works and interviewed him for the catalogue in 2017, Mr. Turner said that unconscious and barely conscious influences went into creating his art, and into appreciating it.
