This is a history of the Liberty Ships that were the work horse for the Allies in WW2. The ships were built in several locations in the US, and while they didn't exist at the beginning of the war, by the end they were being built at record speeds. Several different companies built these ships, but this books concentrates on the California shipyards of Henry Kaiser. Kaiser was the person who build Hoover damn. As part of his innovation in building the ships, he wanted his workers to have access to health care without having travel far, so he created what would become Kaiser-Permanente.
