Steve Ditko is one of the most famous comic book artists and writers of all time. His work for Marvel, Charlton and DC has led to the creation or co-creation of so many wonderful characters. Doctor Strange's early adventures could not have been presented without his distinct and wonderful art.
A recluse who refuses to give interviews (even Jonathan Ross got rejected) has a very strong philosophy and work ethic. Giving his best wherever he worked, even when with penny pinching Charlton Comics where his horror and mystery stories are a joy to read.
I came across this short video on You Tube where Ditko explains his philosophy towards comic book heroes.
