Bengt Edlén

Bengt Edlén (2 November 1906, Gusum – 10 February 1993, Lund) was a Swedish professor of physics and astronomer who specialized in spectroscopy.

He graduated from high school in Norrköping in 1926 and entered the Uppsala University the same year.

[1] He was awarded his bachelor's degree after three semester and graduated with a PhD in 1934 with his thesis about the spectra and energy of the elements in the beginning of the periodic system.

[2] He received international fame after finding unidentified spectral lines in the Sun's spectrum which were speculatively believed to originate from a hitherto unidentified chemical element termed coronium.

His discovery was not immediately accepted, since the alleged ionization required a temperature of millions of degrees.
