Daniel-Alexis-Léopold Grosclaude
Daniel Alexis Léopold Grosclaude whom early French data has addressed at boulevard Notre-Dame, 70, Marseille, département Bouches-du-Rhône, France.[1]
British data has him first as a Merchant, still at the above location.[2]
Slightly later British patent data has him identified as an Engineer.[3]
A type of airship, and the propulsion thereof, was key to his work, with his evolving propeller seen in the accompanying diagrams. Some of his work also reflects the pattern of direct analogy between aerial navigation and submarine navigation and control.[4] Submarine, rather than marine, is key, in that it takes into account factors of the vertical.
