Abstract
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.
