NSERC's Canada Gold Medal for Science and Engineering was first awarded in 1991 to Raymond Lemieux, a chemist working at University of Alberta. [6] Mathematician James Arthur from the University of Toronto was the 1999 recipient, [7] the last year before the award was renamed in honour of Gerhard Herzberg, the winner of the 1971 Nobel Prize in Chemistry.

Gerhard Herzberg 1969 "For his outstanding contributions to physics and chemistry, especially in the field of atomic and molecular spectroscopy as exemplified by his work confirming the predictions of quantum electrodynamics, by his investigation of dissociation and pre dissociation phenomena, and by the publication of his life's work ...
Two others have won Nobel Prizes twice, one in chemistry and one in another subject: Maria Skłodowska-Curie (physics in 1903, chemistry in 1911) and Linus Pauling (chemistry in 1954, peace in 1962). [6] As of 2023, the prize has been awarded to 192 individuals, including eight women (Maria Skłodowska-Curie being the first to be awarded in ...

In chemistry, bond order is a formal measure of the multiplicity of a covalent bond between two atoms. As introduced by Gerhard Herzberg, [1] building off of work by R. S. Mulliken and Friedrich Hund, bond order is defined as the difference between the numbers of electron pairs in bonding and antibonding molecular orbitals.
