worked for Funnies Inc (where his only known credit is working on the
Human Torch Vs. Sub-Mariner story in 1940 and the Human Torch in 1941).
In 1950, he was editor at Fox (apparently the last editor there, before
their bankruptcy)
worked for Lev Gleason in 1951
worked for Timely-Atlas from 1951 -1954
worked for DC from 1959 to 1967, where he wrote backup war stories, Sgt.
Mule, and Sea Devils, and apparently some Batman in the early 1960s.
"Chapman as a scripter goes back to the Timely years,
where he's credited as far back as one of the Torch/Namor crossover battles
in the early 1940's. I've placed him later in the 1948-49 period also. " - Doc V.
