TLS in French, signed “M. Curie,” one page, 5.25 x 8.25, Faculte Des Sciences De Paris letterhead, January 29, 1930. An untranslated letter to Yale Physics professor Alois Kovarik in which she mentions fellow chemist and physicist Bertram Boltwood who pioneered the concept of carbon dating. In fine condition, with a bit of light handling wear. Accompanied by the original mailing envelope, as well as two original postcard photos, one of the Radium Institute and one of the Hotel Radium in Jachymov, Czech Republic; one of Curie’s personal calling cards; a vintage unsigned 6.5 x 9 photo of Pierre Curie; and several clipped newspaper articles. Wonderful association to the historical roots of what became the original definition of the curie. Pre-certified PSA/DNA and RRAuction COA.
