Description

French physicist (1878-1953) who worked on a range of experimental physics topics including magnetic effects on the optical properties of materials and the effects of low-temperature on magnetic susceptibility; the son of Henri Becquerel. ALS in French, one page, 5.25 x 8.5, Museum National d'Histoire Naturelle letterhead, April 19, 1931. Handwritten letter to a colleague, evidently fellow physicist, Aimé Auguste Cotton (1869-1951), in part (translated): "I am very grateful to you for presenting my message to the Academy, and I thank you for your remarks about the book. It would seem to me that one could posit: rotational power along the optical axis of certain uni-axis crystals, near the absorption bands, subject to the action of a magnetic field normal to that axis. We can talk about this tomorrow, by the way, because I will be coming to the meeting. If you have a few moments, I will be happy to share the observations with you that I have made over the past few days and that will render the properties of this effect more precise. Please give my kindest regards to Madame Cotton." In fine condition.
