Louis Harold Gray was a prominent mathematician and physicist known for his significant contributions to understanding the effects of radioactivity on the human body. He was awarded a PhD from the University of Cambridge in 1930, focusing on the absorption of hard gamma rays. Gray later established the field of radiobiology and became the director of the British Empire Cancer Campaign research laboratory. In honor of his work, the SI unit gray (Gy) was named after him, representing the radiation dose that leads to the absorption of one joule of energy per kilogram of tissue.
