Christmas at Hogwarts was quite a magical season, at least in novelist J.K. Rowling’s imagination. Warm fires blazed in the hearths inside the school’s Great Hall and the ceiling was transformed into a dazzling mirage of falling snow.

But as Jewish people around the world prepared to celebrate Hanukkah, one Harry Potter fan from Chicago had a question — were there any Jews at Hogwarts?

For the answer, Benjamin Roffman went directly to the source — Rowling herself.

Anthony Goldstein was a part of Dumbledore’s Army and fought alongside his comrades at the Battle of Hogwarts.

When lighting a Hanukkah candle tonight, remember brave Goldstein!
