There’s not a lot of information available on the artist Richard Tennant Cooper.  It’s known from 1910 to 1912 that he painted several paintings that were meant to show the effects of disease on the human body.  In his paintings, disease was represented by skeletons and evil ghosts, which are often seen hovering above the sick.  Cooper also served in the British Army during World War I and painted several pictures based on his experiences.  The first five pictures below are examples of Cooper’s medical work while the final four were inspired by World War I.
