Manfred Klopfleisch studied physics in Jena and started in 1963 as a scientific assistant at the Institute of Physics of the Technische Universität Ilmenau. After his doctorate "On the influence of electric fields on the luminescence of manganese1 activated ZnS-type phosphors", he became a senior scientific assistant in 1972. In 1973 he completed a half-year additional study at the University of Irkutsk and from 1974 he headed the practical course for experimental physics in the Scientific Department of Physics of the section "Physics and Technology of Electronic Devices" at the TU Ilmenau.

Since 1978, in addition to his teaching duties – which, apart from supervising the practical course, included exercises in experimental physics, lectures on solid-state luminescence, magnetism, electrodynamics of continua and optics – he again devoted himself increasingly to research in the field of thin-film optics. The focus was primarily on theoretical and experimental-methodological problems of optical spectroscopy under excitation of surface polaritons in thin-film systems. With the establishment of an optical laboratory and an own research group, five dissertations, fifteen diploma theses and more than forty scientific publications as well as five patents have been produced since 1981. Two successfully completed industrial research projects and the organization of a national school conference "Surface Polariton Spectroscopy and Optics of Thin Films" in 1987 were honored with a research award from the TH Ilmenau in the same year.

In 1992 he habilitated with the topic "Theoretical and experimental investigations of the properties of electromagnetic waves in plane thin film systems and their use in surface polariton spectroscopy."

Devoted to science with heart and soul, Dr. Klopfleisch found his way back to full professional life after a prolonged serious illness. Until his retirement in 2003, he was a valuable teacher and discussion partner for students, colleagues, especially in the optics lectures, seminars and practical courses, who critically evaluated every result scientifically and never let himself be distracted from his straightforwardness.

The TU Ilmenau mourns the loss of a valued dedicated colleague, recognized scientist and teacher, who rendered outstanding services to the Institute of Physics. We will keep him in grateful memory.
