Jerome Horwitz, the Detroit-area scientist who invented AZT, died Sept. 6 in Bloomfield Township, Mich. He was 93. Horwitz created AZT in 1964 hoping it would be an effective treatment for cancer. When it did not work, he shelved the drug and never bothered to patent it -- only to watch it become the foundation for antiretroviral treatments in AIDS patients more than 20 years later, for which he never earned a penny.
