Crocco, Gaetano Arturo (1877–1968)
Leading Italian aeronautical and aerospace designer, military officer (rising
to the rank of general), and founder of the Italian Rocket Society in 1951.
Crocco designed a number of airships in the early part of the 20th century
and switched to designing rocket engines in the 1920s. Among his many contributions
to the theory of spaceflight was a paper in which he showed that a spacecraft
could, in theory, travel from Earth to Mars,
perform a reconnaissance Mars flyby (that is, not stop over in Mars orbit),
and return to Earth in a total trip time of about one year.1
