Gustaf Ising (or Gustav Ising in some publications), (19 February 1883 in Finja – 5 February 1960 in Danderyd), was a Swedish accelerator physicist and geophysicist.[1]

Ising earned his first academic degree (filosofie kandidat/Bachelor of Arts) at Uppsala University in 1903 and continued studying at Stockholm University[2] receiving his Ph.D. in 1919,[3] later becoming a full professor in 1934.[4]

He is best known for the invention of the linear accelerator concept in 1924,[5] which is the progenitor of all modern accelerators based on oscillating electromagnetic fields. His article was then taken up and turned into practice by Rolf Widerøe,[6] also starting the development of cyclic accelerator structures like the cyclotron and the betatron.

He was elected to the Swedish Academy of Sciences in 1935, being a member of the Nobel Committee for Physics from 1947–1953, together with former Nobel Laureate and chairman Manne Siegbahn, Svante Arrhenius, Erik Hulthen, Axel Edvin Lindh, Ivar Waller, and Gudmund Borelius.[7]
