  Hannes Olof Gosta Alfven
Alfven was educated at Uppsala University and in 1940 joined the staff of the Royal Institute of Technology, Stockholm.
In 1939 Alfven published his theory of magnetic storms and auroral displays in the atmosphere, which immensely influenced the modern theory of the magnetosphere (the region of the Earth's magnetic field).
Alfven was an early supporter of "plasma cosmology," a concept that challenges the big-bang model of the origin of the universe.

 HANNES ALFVEN Hannes Alfven
Hannes Alfven, winner of the 1970 Nobel Prize in Physics,acknowledged as one of creative and intuitive intellect's of the 20th century, died peacefully Sunday evening, April 2, 1995 in Stockholm, Sweden.
Alfven was the first to predict (in 1963) the large scale filamentary structure of the universe, a discovery that confounded astrophysicists in 1991 and added to the woes of Big Bang cosmology.
Hannes Alfven has played a central role in the development of several modern fields of physics, including plasma physics, the physics of charged particle beams, and interplanetary and magnetospheric physics.

It criticized earlier speculations concerning cosmic radiation because they did not "seem to be in accordance with the latest experimental results", and he stated that it should be possible to "explain the origin of the cosmic rays, introducing no new hypotheses, and only applying the kinetic gas theory to the conditions of world space".
This was typical of the spirit of Hannes Alfvén; when the Bowie Medal was bestowed upon him, he responded by giving the Alpha-Centauri Medal to the AGU for safekeeping and eventual placement.
Hannes Alfvén, with his wife Kerstin, also took an active interest in important matters outside science, especially those related to environment, population growth, and disarmament.

Hannes Alfven pioneered the development of MHD, the study of the motion of an electrically conducting fluid interacting with magnetic fields, and, in particular, the subject of plasma physics, the branch of MHD in which the fluid under study is a highly ionized gas consisting of nearly equal numbers of positively and negatively charged particles.
Alfven was chiefly concerned with plasmas in stars, in the geomagnetic field, and in interplanetary and interstellar space, but his theories were basic to the study of laboratory plasmas encountered in the development of controlled thermonucelar fusion.
Alfven pioneered theoretical research in the field of magnetohydrodynamics, the study of the interaction of conducting fluids and magnetic fields, for which he received the 1970 Nobel Prize in physics with Louis Neel.

 GENERALIZATION OF MAGNETOHYDRODYNAMIC THEORY
Abstract: Almost half a century after Alfven conceived of the science of magnetohydrodynamics, it is still possible to trace his intuitive thinking to explore physical processes heretofore not considered.
What is more, this extolling of Alfven based on an enumeration of his ideas and their striking successes and sad suppressions completely misses the true essence of his scientific genius that is equal to that of Newton, Einstein or Maxwell.
It is that he, Alfven, for the first time, recognized that magnetic field is a consideration of the most rudimentary importance; that the place of magnetic field in the scheme of physics had not been properly understood.

In 1954, Alfven published On the origin of the Solar System which, in 1975, was expanded as Structure and Evolutionary History of the Solar System, co-authored with Gustaf Arrhenius.
Thus Alfven states "In cosmic physics, electromagnetic processes have recently attracted a rapidly increasing interest, and it is now generally realized that they are of fundamental importance.
Alfven goes on to point out that it was not "until classical electrodynamics had been combined with hydrodynamics to form magneto-hydrodynamics, which further must be combined with plasma physics in order to allow a deeper understanding of electromagnetic phenomena in cosmic physics." (ibid., p.2.)

For example, his proposal of the double layer was, in part, based on his experience with mercury-vapour rectifiers used in commercial, high-voltage DC transmission.

Hannes Alfvén: Dean of the Plasma Dissidents - Anthony L. Peratt
In the world of specialized science, Swedish electrical engineer Hannes Alfvén is an enigma.
Regarded as a heretic by many physicists, Alfvén has made contributions to physics that are today being applied in the development of particle beam accelerators, controlled thermonuclear fusion, hypersonic flight, rocket propulsion, and the braking of reentering space vehicles.

 Memoirs Of A Dissident Scientists
The reflections of Alfven on the development of cosmic-ray theory are rather amusing; they reveal how much people and ideas change.
Alfven originally maintained that cosmic rays were of galactic origin.
Alfven concludes his reminiscing with a paragraph that says much about today's scientific environment:

 Successful Predictions Mean Little In Science
We first met Alfven in SF#59,where we commented on his paper "Memoirs of a Dissident Scientist." Alfven is still a dissident, a scientist who has the temerity to claim that cosmic rays have a local rather than galactic origin.
The subject of this entry is not so much Alfven's conflicts with accepted scientific views, but rather whether correct scientific predictions really influence the scientific community's acceptance of theories.
Brush concludes that the continuing resistance to Alfven's work is due to the widely held opinion that his theory is not plausible; that is, it does not conform to the dominant paradigm.
