Was Anderson's discovery of the muon initially misunderstood?
Indeed. The muon, discovered in 1936, presented a curious case. Its mass was found to be heavier than an electron, yet it seemed to behave similarly in some respects, particularly in its interactions with matter. Initially, some physicists, myself included for a time, speculated it might be the particle Yukawa had theorized as mediating the nuclear force. However, further study of its decay properties revealed it was not that particle. The universe has a way of surprising those who think they know it all, and the muon certainly did that, prompting a deeper exploration of particle classifications.
