Louis-Marie Le Dantec
Louis-Marie Le Dantec was an aero inventor, whom fairly early British data gives as a priest addressed at rue de Vaugirard, 233, Paris, département Seine, France.[1]
Belgian data has him addressed at rue de Vaugirard, 234, Paris, département Seine, France.[2] The change in street number could suggest a typographical error at either office.
Any elvolution between marine applicability of his propellers and aeronautical applicability is yet to be determined. The propellers do often explicate propeller applicability to ascension as well as to propulsion. The precise physics shown on the patent diagrams also suggest relevance to the subject matter of various pertinent publications. Membership in the clergy, cross-referenced with other data, supports his working with Canovetti, among others.
The precise aerodynamics of these propellers designs is remarkable. There are generally clear enough familial relations across the international spread, with sporadic variance in diagrammatic specifics, as if the theoretical science behind the designs was ongoing concurrently with the patent filings, and at a fast clip.
There is some close relation, both in terms of research and in terms of work with propellers, between Le Dantec and Cosimo Canovetti. Incidentally French patent agent G. Petiau was involved in the work of both inventors.
