Eric Taylor was a screenwriter in the 1930s and 40s. He wrote 1945's Dick Tracy movie and six Universal monster movies, including Son of Dracula.
Before Hollywood Taylor wrote pulp fiction detective stories. Once he had two stories published in the same magazine. One story was published under the pen name Mark Layton.
Taylor did not choose the pseudonym Mark Layton for himself but he continued to publish under that name in his later works.
Taylor died unexpectedly of a heart attack at age 55 in 1952. His wife Virginia wrote a biography of his life. It was never published.
The Eric Taylor papers at UW's American Heritage Center contain scripts and stories that he wrote and Virginia Taylor's biography.
