1. Introduction

Gioacchino Failla (19 July 1891 – 15 December 1961) was an Italian-born American physicist. A pioneer in both biophysics and radiobiology, he was particularly noted for his work on the role of radiation as a cause of cancer and genetic mutation. He was born in Castelbuono in the Province of Palermo and emigrated with his family to the United States in 1906. After his retirement from Columbia University's Center for Radiological Research in 1960, he was appointed Senior Scientist Emeritus in the Radiological Physics Division of the Argonne National Laboratory in Illinois. He was killed in a car accident near the laboratory at the age of 70.^[1][2]
