%0 Journal Article %T On the discovery of the classical equations for spin motion in electromagnetic field %A V. Hushwater %J Physics %D 2014 %I arXiv %R 10.1119/1.4821347 %X The letter addresses misattribution of the discovery of the classical equation for spin motion in electromagnetic field, known as the BMT equation, named after Bargmann, Michel, and Telegdi. I argue that J. (or Ya.) Frenkel, along with L. H. Thomas, should be considered as a co-discoverer of this equation. He first derived it, in another form, in 1926. %U http://arxiv.org/abs/1410.2815v1
