In truth the mastery of flying was the work of thousands of men—this man a suggestion and that an experiment, until at last only one vigorous intellectual effort was needed to finish the work. But the inexorable injustice of the popular mind has decided that of all these thousands, one man, and that a man who never flew, should be chosen as the discoverer, just as it has chosen to honor Watt as the discoverer of steam and Stephenson of the steam-engine.

And surely of all honored names none is so grotesquely and tragically honored as poor Filmer’s, the timid, intellectual creature who solved the problem over which the world had hung perplexed and a little fearful for so many generations, the man who pressed the button that has changed peace and warfare and well-nigh every condition of human life and happiness. Never has that recurring wonder of the littleness of the scientific man in the face of the greatness of his science found such an amazing exemplification.

Much concerning Filmer is, and must remain, profoundly obscure—Filmers attract no Boswells—but the essential facts and the concluding scene are clear enough, and there are letters, and notes, and casual allusions to piece the whole together. And this is the story one makes, putting this thing with that of Filmer’s life and death.
