Undoubtedly the outstanding advance of the last few years in theoretical radio astronomy has been the widespread recognition of the importance of synchrotron radiation by relativistic electrons. The possibility that high-speed electrons might be of importance in the solar problem was mentioned by Giovanelli [1] and by me [2] in 1948. But real quantitative development in this direction dated from the well-known paper of Schwinger [3] published in 1949. Schwinger's results were put into a form suited to the problems of radio astronomy by Alfvén and Herlofson in 1950, still from the point of view of emission from stellar surfaces, however. In 1953, Ginzburg [5] and Shklovskiì [6] took the additional step of suggesting that relativistic electrons exist in space and that they give rise to the emission from nonthermal sources.
