because he had no influence on future developments, whereas the Wrights, for good and ill, certainly did.
One influence the Wrights had was to virtually stop all aviation research and development in the US. With their vigorous legal defences of their patents in court, anyone else who had plans to fly was effectively grounded. This enabled the Europeans to take the lead in aviation. With their ''only just flew'' event, they effectively halted further progress. Perhaps this gives some true insight into their motives - enrichment rather than pioneering.
