Frank Sidgwick (1979-1939) was professionally well-known from the Edwardian era as one half of Sidgwick and Jackson, the publishers. He was also known as a novelist, a humourist, a specialist in light verse, and a parodist. The Times obituary given here sums him up well. Perhaps the most reprinted of his parodies is of ‘Summer is ycumen in’ – you can find the parody here. There is a nice example of his fit with the weekend competition spirit here, where you can also see a photograph.
Sidgwick was also known for his collection of, publication of, and knowledge of the ballad form.
