Heinz Rothe did research and taught at the Institute of Theoretical Physics at Heidelberg University from 1966 until his retirement in 2004, from 1980 as professor. He worked very successfully in the field of theoretical elementary particle physics, especially in the area of quantum field theory and is one of the founders of lattice gauge theory. His research contributions contributed significantly to the reputation of the Institute of Theoretical Physics as a successful center of scientific research and teaching. Heinz Rothe was not only an outstanding and imaginative scientist, but also an always kind and helpful person. His colleagues and students will forever remember him with gratitude and honor.
