What do photo-journalist Grace Robertson and Dick Muir have in common? Lots - considering Dick Muir was Grace's pseudonym when she was first trying to carve out a career in photo-journalism in the 1940's. She sent in her first batch of photos under the name Dick Muir. They were returned. She sent in another batch - which were also returned, but with the note "persevere young man" - which she did.
