who was griffin how did he become invisible
Griffin (The Invisible Man) Griffin is a brilliant research scientist who discovers a formula for making a human being invisible. The formula entails taking opium and another drug, which makes his blood boil, then processing his body in a radiator engine. He succeeds, but he finds himself unable to reverse the process. Unlike the character in the 1933 film, the Griffin of the novel is possibly a psychopath, even before he makes himself invisible.
