Thanks to all who played along with the beards quiz a while back. Figure it's time to give the answers, though there was only one picture that seemed to give people trouble.

The answers:

a. Fidel Castro
b. Saddam Hussein
c. Johannes Brahms
d. Karl Marx

Many thanks to Scott Monty for suggesting Brahms.

There may be a bit of a controversy about the Marx picture. As Matt Boggie writes:

"C, I’m not sure of, and frankly, there’s no way anyone else but me would get D. I’m not quite sure how you got the photo, or how you might know him, but he’s obviously Mr. Clo, the retired band director from Gloversville High School, Gloversville, NY. He also played French horn in the Fulton/Montgomery County Concert Band. He once convinced a young trumpet student of his that he’d had a plastic lung installed in his stomach to allow him to sustain notes longer, which he inflated and deflated by raising and lowering the elbow of his right arm while playing."
