The expression "the father of ...." usually refers to someone who brought the thing referred to to public prominence, or who influenced the study or practice of it more than anyone else. So, the Father of streamlining would most likely refer to an engineer who brought streamlining to perfection in his designs for vehicles... be they cars, trains or airplanes.
Streamlining reduces air resistance by shaping objects to minimize turbulence and drag. This helps objects move more smoothly through the air, reducing the energy needed to overcome air resistance and improving overall aerodynamic performance.
To ensure there is as little friction or drag as possible for example the streamlined helmets that bicyclists wear or the full body swim suits that are becoming popular for swimmers. Swimmers also shave body hair to streamline their bodies and reduce drag.
