Felix Nadar

ALS in French, signed “Nadar,” one page, 5.25 x 8.25, personal letterhead, no date. Handwritten letter by the noted photographer, in full (translated): "Would you be so kind as to grant a mention to this new publication concerning heavier-than-air flight and to forward the issue to your scientific editorial staff." In very fine condition. Nadar coined the term "plus lourd que l'air"—heavier than air—in 1863 to designate flying machines or aerodynes as opposed to balloons.
