Silver Surfer was Norrin Radd, the young man from the planet Zenn-La who saved his home world from Galactus, the planet devourer, by agreeing to act as his herald. This resulted in Norrin flying through the cosmos announcing to various planets that they were about to be destroyed. He later turned on his master, defending the earth. Exiled to the blue planet he spent much of his time shaking his head, ruminating on existence and despairing at the inhumanity of mankind.
Silver Surfer first appeared in a Fantastic Four comic in 1966. When drawn by Jack Kirby a completely silver humanoid with no genitals on a surfboard sweeping through the cosmos, his speech coming from Stan Lee's scripts with him speaking in a kind of Shakespearean English, makes perfect sense.
