  In this paper we present a panoramic view of the main scientific articles
published by Ettore Majorana, the brightest Italian theoretical physicist of
the XX century (actually, Enrico Fermi regarded him as the brighest in the
world of his time, and compared him to Galileo and Newton; even if to some
people Majorana is often known mainly for his mysterious disappearance in 1938,
when he was 31). Extensive information and comments are added with regard to
the scientific manuscripts left unpublished by him. We also outline his life,
the biographical data being based on letters, documents, testimonies discovered
or collected by the author during more than four decades, and contained for
instance in Recami's 1987 book quoted in the text. Two pictures complete the
paper.
