ES-1886 Karl Sax (November 2, 1892 – October 8, 1973) was an American botanist and geneticist, noted for his research in cytogenetics and the effect of radiation on chromosomes. Sax was born in Spokane, Washington in 1892. His parents were pioneer farmers and active in civic affairs; his father was the mayor of Colville, Washington. Sax's early education was in the Colville schools, and in 1912 he continued his studies at Washington State College. He majored in agriculture, and his subsequent decision to undertake graduate work was influenced by the botanist and plant breeder Edward Gaines. In college, he met and married Hally Jolivette, his cytology teacher, and they later had three sons. Following his graduation, Hally accepted a position at Wellesley College in Wellesley, Massachusetts, and they moved to the East Coast in 1916. Sax enrolled in the doctoral program at the Bussey Institution Graduate School of Applied Biology at Harvard University in Cambridge, Massachusetts and completed his MA in 1917. He went on to do his doctoral work at Harvard University, receiving his D.Sc. in 1922. He served as a private in the US Army from 1917 to 1918 in World War I. In 1918, Sax took a job as an instructor in the Department of Genetics at the University of California, Berkeley, where he worked with E. B. Babcock on the genetics of the genus Crepis. In 1920 he took an appointment at the Riverbank Laboratories in Geneva, Illinois working on wheat genetics, but he moved on from that job soon after when he took a position at the Maine Agricultural Experiment Station in Orono, Maine. In 1928 he left Orono to take a teaching position in Harvard's genetics department at the Bussey Institution. However, the department was dissolved before his arrival, and he transferred to the cytology department at the University's Biological Laboratories in Cambridge, Massachusetts. In 1938 Sax published a paper entitled "Chromosome Aberrations Induced by X-rays," which demonstrated that radiation could induce major genetic changes by affecting chromosomal translocations, a chromosome abnormality. The paper is thought to mark the beginning of the field of radiation cytology, and led him to be called the "father of radiation cytology."
