Robert Hale Ives Gammell (1893 – 1981) was an American artist best known for his sequence of paintings based on Francis Thompson's poem "The Hound of Heaven".

[1] Gammell was born into a wealthy family in Providence, Rhode Island and attended Groton prep school.

[2] While recovering, he discovered in Psychology of the Unconscious by Carl Jung a way to approach what he considered his greatest artistic achievement: a sequence of paintings depicting "The Hound of Heaven", a religious poem by Francis Thompson (1859 – 1907).

According to Gammell, in the catalog he wrote to accompany the sequence's first exhibit in 1956, he interpreted the poem not so much as a religious conversion as "a history of the experience known as an emotional breakdown".

He wrote that Jung's work had provided the link between "myths, symbols, and poetic imagery, and the perpetually recurring emotional patterns of human life from which they evolved.

His student, the painter Robert Cormier, said Gammell's classes included the study of anatomy, memory drawing, and the sight-size method.
