HES: QUERY--Dupuit's writings and a question about Mario de Bernardi

[Marcel Claessen]

I have placed a digital copy of the 1933/1934 selection of Dupuit's 
economical writings by Mario de Bernardi [229 pp.] for downloading at 
http://www.condorcet.nl/dupuit1934.pdf. 

I wonder if anyone knows "anything" about Mario de Bernardi? I could 
identify only one [other] Mario de Bernardi: (1893-1959), Italian aviator 
and WW-I ace, known in the U.S. as the "Flying Fascist [according to Time 
Magazine 1959], who held the world speed record in 1926 at 246 m.p.h.,and 
who flew the first Italian jet aircraft in 1940, etcetera: a most 
improbable Curriculum Vitae for an economist - at least in The 
Netherlands. 

With kind regards,

Marcel Claessen
