I do not know of him until such OP specified his works in the post.
A great comic writer now dead. He was such an amazing person. He gave us all so much. I mean the very fantasy that most have being brought to life. The movies that marvel has been able to make. It has been one amazing life for him and he shared that with us. The Hulk, Iron man, Captain America etc.. are all such great hero's that could probably never be replaced in the realm of comics.
Yeah it seems that these are great works of one that has a great imagination. RIP
