Boy on a Broomstick
I read a story the other day about a boy who had magic lessons in school. He liked to ride his flying broomstick, but when he didn't behave his aunt and uncle, with whom he lived, took it away, grounding him in a very literal manner. His nasty cousin kept telling on him. Non-magic technology was barely known to the people in the story, and any investigations into it were discouraged.
The story was published in 1953, twelve years before J.K. Rowling was born. It's called "The Wall Around the World" and was written by American sf writer Theodore R. Cogswell (1918-1987). In 2003 it was nominated for a retro-Hugo for best novelette of 1953 (the award went to James Blish). Given the general state of sf in 1953, I suppose it's pretty good. But I like Harry Potter better.
Mike Ashley has made the same connection, but he doubts that J.K. Rowling read Cogswell's story before conceiving of H.P.
