Born in Milan, Luigi Corteggi began his career in the advertising field. He had his own studio for five years, before he switched to comics in the early 1960s, starting with a collaboration with L'Intrepido. In 1965, he joined the Corno publishing house, and illustrated stories with 'Kriminal', 'Satanik' and 'Gesebel'. He drew most of the covers and some of the stories for the 'Alan Ford' series.
In 1980, he illustrated the science fiction story 'L'Astronave Perduta' with a script by Giorgio Pezzin. A year later, he created 'Benigni a Fumetti'. He was art director at Bonelli since 1975, and was responsible for series like 'America' and 'Un Uomo un'Avventura'.
