Hunagarian-born Raoul J. Hoffman was an engineer who had worked on Laird Super Solution among other projects. He played a significant role in taking the sketches of podiatrist and aviation enthusiast Dr. Cloyd Snyder, who had noticed that his D-shaped foam heel lifts flew quite well, and bringing them to life as the Arup series of aircraft. Hoffman also designed and continued to promote low aspect-ratio aircraft on his own. Later in life, he was a active member of the Experimental Aircraft Association and many of his articles, not only on low aspect-ratio aircraft but also on everything from wingtip styles to types of riveted and welded joints, are includes in the EAA design series of books assembled from the early Sport Aviation articles of the 50s and 60s.

Here's a link to the English Language Google Books page for this aeroplane:

Flying Magazine

Raoul J. Hoffman; "A Novel All-Wing Airplane", Popular Aviation, March 1935, pp.163 and 196.

Note that: a) Google Books is wrong about the magazine title at the time, and b) the plane is is not all-wing, Hoffman (or the editor) is mistaken. It is a tailless aeroplane, and no more.
