1. Don't know, don't care. Half the time I con't even know if the author is a man or a woman because they just use initials for their first and middle name. TH White, KA Applegate, RA Salvatore, CS Goto, JK Rowling, JRR Tolkein, etc etc etc
And then names that aren't what you'd assume, like Tracy Hickman and Sandy Mitchell are guys.
And then gods know how many of them are pseudonyms.
Obviously I'm familiar with some of them, but others...*shrug*
2. Happens occasionally. Read enough classic stuff and it's inevitable. Homer, Sun Tzu, Musashi, Victor Hugo, Alexandre Dumas, Jules Verne, the Brother Grimm, Anne Frank, Michael Ende, Nietzsche, Kafka, whoever wrote Beowulf, etc etc etc.
