Collapsible B Fireman 1 was a fictional stoker aboard the Titanic, he was portrayed by Bill Reick.
He first appears aboard the upturned Collapsible B, preventing Harold Bride from climbing aboard, whacking another person with an oar. He is grabbed by another man on the boat and stopped from injuring Bride. Second Officer Lightoller then told them to help Harold into the boat. It seems that he may have fallen off the boat, but the shot is not clear, so his fate is unknown.
