That reminds me of Isaac Asimov's[0] story in Asimov Laughs Again about being confused with Arthur C. Clarke[1]. They had similar writing styles, so it was quite common for Isaac's books to be attributed to Arthur and vice versa. Childhood's End[2] was Arthur's most popular and well-known novel at the time.

At a science fiction convention, a woman said to me, "Dr. Asimov, I have just finished your book Childhood's End. I liked it, but I didn't think it was as good as your other books."

Maintaining a straight and solemn face (with an enormous effort), I said, "Yes, ma'am. I was frightfully disappointed in that book, which I thought was quite inferior. I therefore insisted it appear under the pseudonym of Arthur C. Clarke, Jr."
