Haggi aka Jehrum aka Der Bub was born in 1961 under the pseudonym Hartmut Klotzbücher in the Swabian Alb. He writes, edits, translates and draws comics. Probably his best-known character is Hartmut, a little boy with an idiosyncratic spelling, whose adventures appear regularly on the Gringo Blog and in anthologies published by Gringo Comics. After a long break, he has also resumed work on the Adventures of Dear God, his own interpretation of the Old Testament.
