This states that the firm likely was closed on Purdy's death (ref.2). The firm was in business at the time of the NY World's Fair and much after. My father joined the firm after graduating from MIT in 1928 only to be laid off as the Depression took hold. He rejoined the firm some time later--not sure when--a couple of years I expect. He stayed with P and H to rise to president. When he retired the firm was still in business. I do not have dates to provide at present--I will see if  I can get some. I did find a document which at least demonstrates the firm being in business at the time of the Fair.

The Fair is firmly in my mind because I know that the firm was responsible for inspecting the construction drawings for the pavilions. I was present when my father received a phone call about the pavilion collapse. He found that he had specified some diagonal bracing be added. They had not added the bracing. News items of the time left out that detail.

His name is Wallace H. Heidtmann
