Andrei Severny working outdoors on his research

Prof. A. B. Severny, that most durable and notable of Soviet solar astronomer, caught briefly between his day in the office and night at the telescope. Best known for his work on solar magnetism he is no longer content with only the sun, but now is seeking to measure the magnetic fields of stars. Applying the techniques of the (solar) photo-electric magnetograph, he is able to achieve sensitivities of but 15 Gauss for bright stars -- which he investigates regardless of spectral type. The perfect host, Severny held off a rejuvenation of his solar tower for two months in order that the writer might inspect and participate in a day's observation. He is now installing new mirrors of zero-expansion pyro-ceramic material, with increase of aperture from .40 to 1.6 m.In the European tradition of the Distinguished Professor, Severny steers and dominates the research at Crimea. The fruit of this leadership has been their pioneering role in solar magnetic research. A negative consequence of this system is that the professor's prejudices pervade through the staff. For example, Severny has long been skeptical of Leighton's supergranulation concept. Now generally accepted, and I believe quite useful, the idea is selfom acknowledged in a Kp.A.O. paper.I was pleased to find that Severny, although hard pressed by administrative duties, still remains intimate with the observing and reduction work. He has two offices, well separated: one of Director and one for science.
