Izrael Hieger DSc (London) (13 June 1901 – 14 October 1986) was a biochemist whose work focused on carcinogenesis. He discovered the first known organic carcinogenic compound. In 1937 Hieger, with colleagues Ernest Kennaway and J. W. Cook, was nominated for a Nobel Prize for work on isolating chemical carcinogenic agents from tar and studies on the relation between chemical constitution and carcinogenic activity.

Hieger was born in Siedlce, Russian Empire (present Republic of Poland), and was the youngest of nine. Preempting the

Career

In 1924 Hieger joined Kennaway at the Cancer Hospital Research Institute (CHRI). In pioneering work with W. V. Mayneord, the hospital's medical physicist, Hieger discovered the first known organic carcinogenic compound. Exploiting a method of fluorescence spectroscopy indicated similar spectra for carcinogenic tars and 1,2-

(PAHs). In 1931 Hieger painstakingly obtained 7 g of crystalline hydrocarbon from two tonnes of gas-works soft pitch. This was identified as 3:4- benzo(a)pyrene, and highly carcinogenic. The discovery confirmed concerns over the correlation between occupational cancers and industries which involved exposure to tar, coal-gas and synthetic dyes In 1939, Hieger and four colleagues, ( Kennaway, Mayneord, J. W. Cook and C. L. Hewett) were awarded the first Anna Fuller Memorial Prize for cancer research."Cancer Research"
