Russell Earl Marker (March 12, 1902 - March 3, 1995) was an American chemist who invented the octane classification system while working at Ethyl Corporation. Later in his career, he contributed to the steroid industry in Mexico by successfully synthesizing semisynthetic progesterone from chemical constituents found in Mexican yams, a process known as Marker's degradation. His work ultimately led to the development of oral contraceptive pills and synthetic cortisone and played a significant role in the commercialization of Mexican barbasco.
