Hannes Alfvén is visiting professor of Physics at the University of California at San Diego.

Hannes Alfvén receives one half of the 1970 Nobel Prize in Physics "for fundamental work and discoveries in magnetohydro-dynamics with fruitful applications in different parts of plasma physics". The other half of the price is given to Louis Néel "for fundamental work and discoveries concerning antiferromagnetism and ferrimagnetism which have led to important applications in solid state physics".

Hannes Alfvén is appointed lecturer in physics at Uppsala University.

Hannes Alfvén dies in Djursholm at the age of 86.

Hannes Alfvén becomes research physicist at the Nobel Institute for Physics in Stockholm. In 1937, he hypothesizes that if plasma pervades the universe, it could then carry electric currents capable of producing a galactic magnetic field.

Hannes Alfvén is appointed Professor of Electronics.

Hannes Alfvén is appointed Professor of Plasma Physics. Alfvén is an early supporter of “plasma cosmology”. According to those who endorse this theory the universe has no beginning and no foreseeable end. Plasma—thanks to its electric and magnetic forces—has done more to organize matter in the universe into star systems and other structures than has the force of gravity.

Hannes Alfvén earns his PhD at Uppsala University. The title of his dissertation is "Investigations of the Ultra-short Electromagnetic Waves".

Alfvén Hannes publishes his theory of magnetic storms and auroral displays in the atmosphere. He discovers a widely used mathematical approximation through which the spiral motion of a charged particle in a magnetic field can be easily calculated. Alfvén is a pioneer of Magnetohydrodynamics (MHD), the study of plasmas in magnetic fields, and his work has been acknowledged as fundamental to attempts to control nuclear fusion.

Hannes Alfvén is born in Norrköping, Sweden from Johannes Alfvén and Anna-Clara Romanus. Both his parent are practising physicians (his mother is one of the first female physicians in Sweden). One of his uncles is a famous composer, another an inventor, and a third, an agronomist by profession, very interested in astronomy and environment’s problems.

Hannes Alfvén joins the Royal Institute of Technology where he is appointed Professor in the Theory of Electricity. In 1945, Alfvén Hannes becomes Professor of Electronics.

Hannes Alfvén is a Fulbright Scholar at the University of Maryland, College Park.

Hannes Alfvén develops a theory concerning the origin of the solar system in 1942, and later in the 1950s. He assumes that the solar system has formed from a magnetic plasma, which condensed into small particles that assembled together into larger bodies. He also suggests that waves, now known as Alfvén waves, can travel through a plasma under conditions similar to those in the solar atmosphere.
