The concept of antimatter is extremely important, but not always discussed as it deserves, balancing ideas and formalism. In this note, we gather some insights to present it effectively, following certain steps taken in the history of knowledge; although rarely remembered, they can serve to enrich standard teaching materials. In addition to the well-known contributions of Dirac, which we place in their original context, the contributions of Pauli and especially Majorana stand out, the latter being the first to reach the modern formalism of canonical quantization. The importance of the point of view of wave mechanics emerges, which still shows its limitations, requiring some adjustments to constitute an acceptable interpretation.
