À terre & en l'air...

A vivid memoir that plunges listeners into the daring world of mid‑nineteenth‑century flight, this work follows the adventurous spirit of a pioneering photographer‑inventor who dared to lift himself and his ideas into the skies. Through lively prose and detailed sketches, he explains the mechanics of balloons, the promise of steam‑driven propellers, and the natural lessons drawn from birds that inspired his vision of powered aerial travel. The narrative captures the excitement of early experiments, the challenges of balancing weight and lift, and the bold optimism that propelled his quest for a practical flying machine.

Beyond the technical musings, the memoir offers a window into the formation of the first society devoted to air locomotion, introducing the eclectic cast of scientists, engineers, and dreamers who rallied around the project. Readers hear vivid accounts of daring ascents, the harsh realities of early test flights, and the persuasive arguments that convinced skeptics to support the cause. The author’s blend of scientific insight and personal conviction makes this a compelling portrait of an era when the sky first seemed within human reach.
