When Card David Anderson discovered a new particle with a mass between that of the electron and proton, he named it ‘mesoton’ in a 1933 publication in the Physical Review. However, on the advice of Professor R.A. Millikan, he changed the name to ‘mesotron’ although he (Anderson) did not agree with it. Homi Jehangir Bhabha then sent a short paper to Nature journal in February 1939 in which he proposed the name meson.
