First to 20 hours

Who was the first man to fly 20 hours in competition? I believe it was Wilf Lovatt of Stoke-on-Trent but anyone can correct me if I am wrong. I came across information and posted it in the "Tippler Information" or forums section under information about Wilf Lovatt. It is also attached to this blog post. It was interesting to learn that he completed his 20 hours to the rules in 1963 but without any electric lighting used. His loft did not have any electricity. Photo by B Funk in 1972.
