Description  

French Catalan mathematician, physicist, astronomer, and politician (1786-1853). ALS in French, signed “F. Arago,” one page, 8 x 10.25, August 25, 1839. Letter to an Italian astronomer and mathematician Giovanni Plana, director of the observatory of Turin, recommending French officer and engineer Guillaume Piobert. In part (translated): “He is an officer full of merits with whom, in addition, you can talk about transcendental analysis, mechanics, astronomy, physics and you shall never be afraid not to be understood." Addressed on the reverse of the second integral page in Arago’s hand. Intersecting folds (one vertical fold passing through a single letter of the signature), light soiling, and toning from the wax seal, otherwise fine condition. This dates to the same week that Arago revealed the revolutionary processes behind Louis Daguerre’s photographic experiments before a joint session of the Academie des Sciences and the Academie des Beaux-Arts. Good content with several desirable scientific associations. Pre-certified PSA/DNA.
