A man believed to be Arthur E. Gruhl, technician at the Fir Door Institute, tests a full sized door at the Plywood Research Foundation laboratory in September, 1951. Douglas Fir plywood was constantly being tested for durability and to maintain high standards of quality production. The Douglas Fir Plywood Association, based in Tacoma, set up the Plywood Research Foundation as an industry maintained quality control laboratory.
