"All ex-students, all signed. You'll notice Barnabas Cuffe, editor of the Daily Prophet, he's always interested to hear my take on the day's news."
-- Horace Slughorn, showing Harry his collection of photographs (HBP4)
Barnabas Cuffe was editor of the Daily Prophet (HBP4).
He was one of the famous ex-students "collected" by Horace Slughorn, and had given him a signed photograph. He was probably a member of the Slug Club when at Hogwarts (HBP4).
