In the present work the multilateral  activity of Prof. Dr. Rasum Andreichin is exposed. This activity is in different institutions, but mostly in Sofia Universiry and Bulgarian Academy Sciences. He has service in the creation, defences and development of the physics of dielectrics and semiconductors, including  vitrious semiconductors, agrophysics,    photometry, colorimetry, optical metrologia. Together with Acad.Georgi Nadjakov he is  discoverer of the contact – potential photovoltaiс effec in wide gap semiconductors,,as and  discoverer of the photoelectric state in vitrious semiconductors
