Considered the founder of the science of lubrication, his namesake equation is used as the basis for turbulent flow analysis, though he might be better known for another concept that, if greater than 3000, determines turbulent flow and, if less than 2000, determines laminar flow.  
He became the first full-time Professor of Engineering in England at the age of 26 and dedicated most of his work to solving everyday problems as demonstrated by his "Sewer Gas and How to Keep it Out of the House."
