I don't know why you mention the name of John Collier, as he had nothing to do with any information on Sam Risien. If you would check the site, you would see the sources of information that I had obtained, which, coincidentally, is my mode of operation, namely, properly citing the sources consulted of all data I use.
This is to ensure that I am not falsely accused of plagiarism, and I place emphasis on the word "falsely!"
