Eberhard Kranemann (also known as Fritz Müller; born 7 Marth 1945) is a German artist, musician and a former member of Kraftwerk.

He studied classical double bass at the Dortmund Conservatory, playing Bach/Mozart/Telemann-orchestra music and with jazz bands. Then he went to Düsseldorf to study painting at the Arts Academy. Besides experimenting with colours and painting abstract pictures, he experimented with sounds, at first on cello, clarinet, tenorsaxophone, electric guitar, hawaii guitar, later with electronic instruments. In 1967, with other art students he founded the experimental music group Pissoff.

At this time Florian Schneider heard the sound of the group and joined the band, becoming a friend of Eberhard Kranemann. After four years of collaboration he began to work with Klaus Dinger and Michael Rother in the band Neu!.

Later on he invented for himself the stage personality Fritz Müller, working as a solo artist in concerts and recording at the Conny Plank studio in Wolperath. He formed the Fritz Müller Band, did concert tours, more studio work, radio and television appearances.
