Ludwig Galea is a Maltese singer who along with Julie Zahra represented his country in 2004 Eurovision with "On Again, Off Again". They qualified from the first ever semi final and cracked the Top 10.
Ludwig von Drake, a Disney duck character. Some fans speculate that Ludwig is Scrooge McDuck's brother-in-law through Scrooge's sister Matilda. But Matilda's creator, Don Rosa, has never used Ludwig in any of his stories, and he makes it fairly clear that Matilda never married. If Ludwig is related to the Duck family, it's likely through Daisy Duck, or through Donald's paternal line.
The personification of Germany in the four-panel webmanga/anime series Axis Powers Hetalia is called Ludwig. I don't remember his last name though, cause I fail. XD;
"Ludwig Kakumei" by Yuki Kaori is about a perverted prince (named Ludwig, of course) who searches for a suitable princess to marry, with his childhood servant, Wilhelm. In the beginning he's a necrophiliac. He drops that hobby soon, though. It's an awesome manga XD. And I really like how this name sounds too.
Another famous bearer was Ludwig Friedrich Wilhelm II, King of Bavaria. He is famous for his wild imagination and castles, for example Neuschwanstein (which the Disney castle was based on). He was deposed from the throne on grounds of mental illness. After he left on a walk with his doctor, both of their bodies were found floating in Lake Standberg.

I'm quite surprised nobody's said anything about Ludwig van Beethoven in the way of famous bearers. He's mostly known as the classical composer who went deaf but still continued to compose his music despite his disability.
