You've probably heard of Stan Lee. You may not have heard of Steve Ditko, even though the two worked side by side for many years. During the time that Ditko and Lee worked together, some very important, culturally significant comic strip creations were born. Specifically, Ditko is credited as the co-creator of 'Spider-Man' and 'Doctor Strange'. We're watching movies in 2018 based on things Ditko drew nearly sixty years ago.
Part of the reason that Ditko may be an unfamiliar name is that he shunned the spotlight. Firstly, he and Lee fell out in the late 60s and went their separate ways, so Lee never speaks about him. Secondly, Ditko was such a recluse that when the BBC made TV movie called "In Search of Steve Ditko" in 2007, he refused to appear in it! Such was his legacy that both DC Comics and Marvel paid tribute to him after his death at the age of 90.
