After the Bauhaus was shut down, Grabe joined van Beuren, Morley Webb and others (Albers, Meyer) and emigrated to Mexico City where they worked together (daybed for the '41 Organic Design in Home Furnishings competition). He left Mexico after a few years for the USA, worked in architecture and furniture design and wrote books on the subjects (Build Your Own Modern Furniture).
He lived in New York, where he ran "Klaus Grabe, Inc." 719 Lexington Avenue selling furniture, parts and furniture plans by mail order. Obviously he gained some fame in the low-cost and DIY furniture scene, there are several features on his designs in Life, Popular Science and similar magazines.

You're right, it's hard to...
You're right, it's hard to find any facts on the lesser known bauhaus-people, but I can recommend google books as a source. They have scanned a lot of books and magazines. The NY Times has a searchable archive for all issues as well. Despite all difficulties I still love to to research, but more in actual libraries, scanning through old books and mags or microfilms, actually feeling and smelling the age!
Generally it would be nice to have a book that traces the routes of former bauhaus students throughout the 20th century to see how the influence spread around the world as many of them had to leave Germany and established elsewhere. The lives and work of the well known icons is well documented, but it would be wrong to limit the bauhaus movement to those few (though I respect and admire their role as innovators and idols).
There where so many bauhauslers and I think they had their share of influence on design history and spread the spirit as well. Just look at the part of Grabe & friends in laying the foundations in modern Mexican design (domus)...
Klause Grabe Plywood Chair Design from 1949
Here is an example of the chair design as published in the December, 1949 issue of Popular Science Magazine. It is one several pieces that Mr. Grabe designed for this article on building economical furniture.
It was easy to lay out on a 4 ft. square piece of 3/4" thick pine plywood, as they were delineated in the magazine illustrations. I laid the plywood on a 3' x 5' utility table and used a Stanley "Sharptooth" 15" hand saw to cut the pieces. Some edges were a little erratic so I used a block plan to smooth. Assembly was very easy and quick with white glue and 1 1/4" or 1 1/2" finish nails and a few csk. flathead wood screws. It really is easy to build.
The chair sits surprisingly well and is quite sturdy. Mr. Grabe was a talented designer, for sure. One can adjust angles and height by trial and error. As designed, the armrest height is too low for me so I will recut/rebuild the side pieces a bit taller. Not yet sure what the finish will be. You can find this PS issue on Ebay from time to time.
