Louis Harold GrayFRS (10 November 1905 – 9 July 1965) was an English physicist who worked mainly on the effects of radiation on biological systems. He was one of the earliest contributors of the field of radiobiology.[6] Amongst many other achievements, he defined a unit of radiation dosage (absorbed dose) which was later named after him as an SI unit, the gray.[7][8]
Early life
Gray was born as an only child on 10 November 1905 to parents Harry and Amy Gray. His father worked at a post office.[9]
1953 - Oliver Scott established the British Empire Cancer Campaign Research Unit in Radiobiology[13] at Mount Vernon Hospital with Hal Gray as director which in 1970 became the Cancer Research Campaign's Gray Laboratory and then (in 2001) the Gray Cancer Institute.
1953 - 1960 - Under Gray's direction, Jack W. Boag developed pulse radiolysis[14]
1962 - Ed Hart, of Argonne National Laboratory, and Jack Boag[15] discovered the hydrated electron using pulse radiolysis at the Gray Laboratory - This discovery initiated a new direction of research that is still very active today and is vital for understanding the effects of radiation on biological tissue, for instance in cancer treatment.
