Due to the failure of its developer to write in anything but his native language, the work behind this concept went largely unnoticed until 1889, and some of the behavior predicted by it wasn't fully explained until the work of Morris Selig Kharasch in 1933.

Its discovery was the result of research done on the prediction of regioselective addition reactions of hydrogen halides.  Stating that reactions occur via protonation to give the more stable carbocation, FTP, identify this rule of organic chemistry that states hydrogen adds to carbons with more hydrogens, originally stated by its eponymous Russian discoverer.
