That only speaks for the 1800s, though. There were a lot of incorrect beliefs among scientists during that time that weren't commonplace before; race biology comes to mind.
Soap has been around for a long time, and thousand-year-old religions have rules about cleaning oneself. My impression was that doctors actually stopped believing in disinfection during the rise of modern science, as they began see these beliefs as unscientific superstitions. I don't currently have a source for this, though.
