Samuel Crowell, The Gas Chamber of Sherlock Holmes - An Attempt at a Literary Analysis of the Holocaust Gassing Claim  "Samuel Crowell" is a pseudonym. The author appears to be a mainstream professor (not a professional revisionist) who doesn't want to use his real name. "The Gas Chamber of Sherlock Holmes" is probably the most important revisionist document on the internet. As of January 2005 the CODOH site is back online, and naturally this was one of the first documents restored to the new site.
