‎First apperance of Becquerels first optical paper. Becquerel’s early research was almost exclusively optical. His first extensive investigations dealt with the rotation of plane-polarized light by magnetic fields (the paper offered). He turned next to infrared spectra (in the paper offered), making visual observations by means of the light released from certain phosphorescent crystals under infrared illumination. Becquerel is known for his discovery of radioactivity, for which he received the Nobel Prize for physics jointly with the Curies in 1903, and for other contributions to that field which he made during the halfdozen years when he was most active in it.‎
