I traced Mr. Petersen, at least partially, in the city directories. He stayed at Holt, Renfrew for less than three years, as the 1936 directory lists him as the advertising manager for Langleys (the dry cleaning firm). Amusingly, the 1935 directory lists him as the advertising manager for the "Hotel Renfrew".
He is missing from a few directories at the time of the Second World War, which suggests that he went off to fight. After the war, he gradually worked his way up to forming his own advertising partnerships; he appears in the 1969 directory as part of one. I didn't trace him after that.
