“It is a fact of life that oversimplified accounts of the development of science are often necessary in its teaching. Most scientific progress is a messy, complex and slow process; only with the hindsight of an overall understanding of a phenomenon can a story be told pedagogically rather than chronologically. This necessitates the distilling of certain events and personalities from the melee: those who are deemed to have made the most important contributions. It is inevitable therefore that the many smaller or less important advances scattered randomly across hundreds of years of scientific history tend to be swept up like autumn leaves into neat piles, on top of which sit larger-than-life personalities credited with taking a discipline forward in a single jump. Sometimes this is perfectly valid, and one cannot deny the genius of an Aristotle, a Newton, a Darwin or an Einstein. But it often leaves behind forgotten geniuses and unsung heroes.”
