Rolf Wideroe. Historical portrait of the Norwegian electrical engineer and physicist Rolf Wideroe (born 1902). Wideroe is famous for his work on ion acceleration. He devised a prototype particle accelerator in 1928. Although his was linear, it inspired Ernest Lawrence to develop the cyclotron a year later. A cyclotron is a circular particle accelerator that is more efficient at accelerating particles to high energies. Wideroe mainly lived and worked in Germany and Norway. Photographed around 1920.
