There were many famous pioneers of aviation.
Amongst them....Otto Lilienthal, Octave Chanute, Louis Blerio,Hugo Junkers the famous known ones.
but however only the Wright Brothers are remembered promptly,probably because 1st powered flight was by them.....unfortunately the 3rd guy in the group Charles Taylor that manufactured the engine was not remembered with them.
It could also be possible that there was someone who was more successfull than the above,but whose success was not known publically so History has not given due credit to them.
Your views,since persons from the tech/Ops field would probably have a lot of knowledge on the same.
