Known for	A-Z pregnancy test

Bernhard Zondek (1891-1966) was a reproductive endocrinologist who developed the first reliable pregnancy test in 1928.

Bernhard Zondek was born in Wronke, Germany. He immigrated to Palestine in the 1930s after the Nazis rose to power, settling in Jerusalem. His work with the gynecologist Selmar Aschheim led to his bioassay for human chorionic gonadotropin, originally using mice, known as the Aschheim-Zondek or A-Z test. Later variations on this test used rabbits or amphibians, leading to the phrase "the rabbit died" to describe the discovery of a new pregnancy using the rabbit test. ^[1]

Zondek was one of the earlier proponents of the inter-dependence of the endocrine glands under the control of the pituitary gland.
