Fifty years ago today, we lost Hannes Bok. His lush art style, moving from the highly romantic to the highly grotesque, was derived from his friend Maxfield Parrish and earned Bok an early Hugo award for his cover drawings. His few prose writings were influenced by A. Merritt.
Bok was a strange fellow who became more and more reclusive in his later life. He died, at age 49, from a heart attack or, perhaps, as Forrest J. Ackerman maintained, from starvation.
The link will take you some of his artwork. (Ignore the dates it attributes to Bok; I don't know where the heck those came from.) Gorgeous and imaginative work from a genius who died far too young.
