Hugo Fricke

Hugo Fricke (August 15, 1892, in Aarhus, Denmark – April 5, 1972, in Huntington, New York, US) was a Danish-American physicist who studied the chemical (radiolysis) and biological (radiation biology) effects of X-ray and electron beams[1] and who also invented the Fricke dosimeter named after him.

[3] In 1918, he moved to Lund University where he worked with Manne Siegbahn on X-ray spectroscopy.

He moved to Cleveland Clinic by invitation of George Crile to head a biophysics laboratory between 1921 and 1928.

During his stay at Cleveland Clinic, Fricke and colleagues discovered the radiation response of ferrous sulphate that eventually resulted in the widely used dosimeter named after him.

His research at Cold Spring Harbor Laboratory laid the foundation for the understanding of the radiation chemistry of water.
