Sigurd Hofmann (15 February 1944 – 17 June 2022)[1] was a German physicist known for his work on superheavy elements.

Hofmann discovered his love for physics at the Max Planck High School in Groß-Umstadt, Germany, where he graduated in 1963.

He was the leading scientist with the discovery experiments of the chemical elements darmstadtium (Ds, atomic number 110),[2] roentgenium (Rg, 111)[3] and copernicium (Cn, 112).

[4] He made substantial contributions to the discovery experiments of the elements bohrium (Bh, 107),[5] hassium (Hs, 108)[6] and meitnerium (Mt, 109).

[7] He participated in the discovery of the element flerovium (Fl, 114)[8] at the Flerov Laboratory of Nuclear Reactions (FLNR) in Dubna, Russia, and his research group confirmed data measured on the synthesis of the elements flerovium and livermorium (Lv, 116)[9] at FLNR.
