The text of the book speaks of "Herrick", so I think it's Gerard P. Herrick.
Just have a look here http://www.aviastar.org/helicopters_eng/herrick.php.
The type of the "french designer" looks like the one shown in AirTrails, August 1950, although I have
no other information about the designers name.

The way I understood it, they are all Herrick designs (as in Herrick Convertaplane), and the caption merely states that a French designer also studied a similar configuration.
 
I think Dorand has designed a Triebflugel-type in which the two-bladed rotor converts to wing (and I hope back to rotor)

My dear Jemiba,

the designer may be "de Monge" as I explained before, and from Air Trail.

Is there some more information on these last three images? What year? Who designed this convertaplane built to the de Monge principle? Where were these images published? Looks like they might be from Popular Mechanics or another American magazine of the 1960's.
