This character only appears in about three episodes
of the French series "Mickey à Travers les Siècles"
("Mickey Mouse Time Travel"; the first episode plus two other episodes),
published in "Le Journal de Mickey" from the #15 (September 7th, 1952)
to the #1362 (August 6th, 1978) , (the first 4 episodes were drawn
by Louis "Ténas" Santel, the 5th is both by Ténas and Pierre
Nicolas, all the other episodes were by Pierre Nicolas; the plots were
by Pierre Fallot, and for the latest episodes by Jean-Michel Le Corfec).
So, this character has been created by Ténas, on September 7th,
1952.
He is a dog-nosed professor who invented a liquid which, if you are
given an impact, makes you travel in time. He is a neighbor of Mickey Mouse,
and when he hears him saying, through the wall, that he would have loved
to be a crusader knight, he decides to use him as a kind of guinea pig
(moreover, Durandus tells he is too old and doesn't know France History
enough to try the liquid). Mickey accidentally drinks the liquid . Most
of the episodes take place in France, but there also were a few episodes
which happened in America, England, Canada, Russia,... so it is also a
space travel, not only a time travel.
In 2000, for "Le Journal de Mickey" #2481, a new episode has been published,
drawn by José Antonio Gonzalez and plotted by Gilles Corre, with
Mickey Mouse, Doctor Einmug, Goofy, Minnie Mouse, Donald Duck and Gus Goose.
( In this episode, the Doctor Einmug seems to replace
Professor Durandus. In this story, Mickey meets Charlemagne, Leonardo Da
Vinci, Louis XIV, Shakespeare, Parmentier, Ludwig van Beethoven, Colombus,
and the assembly during the French Revolution.)
In France, it is easy to mistake him with Doctor Einmug, who is called
"Professeur Mirandus", which sounds
like "Professeur Durandus".
