Haggi aka Jehrum aka Der Bub was born in 1961 under the pseudonym Hartmut Klotzbücher in the Swabian Alb. He has been lettering, editing, translating and drawing comics for over 40 years. His best-known character is probably Hartmut, a little boy with an idiosyncratic localography, whose adventures appear regularly in the Gringo blog and in anthologies published by Gringo Comics. After a long break, he has also resumed work on "The Adventures of the Loving God", his own interpretation of the Old Testament. He received the ICOM Independent Comic Award for Best Funny in 1994 for "The Adventures of the Loving God", as well as in 2019 for "Hartmut". He has also received various other nominations. The long-awaited third part of "Die Abenteuer vom lieben Gott" will be published in Erlangen.
