Leo Loeb's Human Design Chart
1/3 Sacral GeneratorAmerican physician, educator, and experimental pathologist, who conducted a series of important experiments on the influence on cancer growth by reproductive hormones. In 1907, Loeb published a study which showed that breast carcinoma in mice could be hereditary, as it is now known to be in some human cases.
Loeb also showed clearly that the growth of certain epithelial malignancies in animals could be modulated by removal of the ovaries. That work predated clinical application of the same concept in human breast cancer by several decades.
He died on 28 December 1959, aged 90, in St. Louis, Missouri.
