Mary Sellers, 27, laces up her heavy boots at the beginning of her eight-hour shift and heads into a coal mine burrowed 725 feet beneath southern Illinois farmland. Some 500 miners work at the Inland Steel Coal Company's Sesser Mine, but only 15 are women, and only one of them—Sellers—is a foreman. (There are fewer than 10 other female foremen nationwide.) For six months Mary has overseen materials and supervised a supply crew of nine men. Born in Belleville, Ill., where her father worked in a Monsanto plant and her mother was a clerk for the Department of Agriculture, Mary graduated from high school in 1971. She spent two years at Blackburn College in nearby Carlinville and last year completed an associate's degree in mining technology. In 1973 she married Ronald Sellers, a divorced welder with three children. The family bounced around the country for a couple of years before returning to Illinois to start a wholesale beauty supply business. When that fell apart, Mary took a surveyor's job with the Freeman United Coal Mining Company. In 1978 she switched to Inland and moved up the ranks from shoveling coal at $9.50 an hour to her present position. It wasn't that difficult, the 5'5" blonde insists: "I just decided I was going to be good enough and strong enough."?

Myung-Whun Chung, 27, associate conductor of the Los Angeles Philharmonic, is the second youngest of the seven gifted siblings of music's "Chung Dynasty." His sister, violinist Kyung-Wha, shared top honors with Pinchas Zuckerman at the 1967 Leventritt Competition in New York. Another sister, cellist Myung-Wha, won the 1971 Geneva International Competition. As for Myung-Whun, he has been awarded three prestigious prizes, including the silver medal at the 1974 Tchaikovsky Competition in Moscow. Born in Seoul, South Korea to two music lovers, Myung Whun was given piano lessons as a toddler. His brothers and sisters diversified their talents, variously picking up the flute, clarinet, cello and guitar, but Myung-Whun remained at the keyboard and at 7 debuted with the Seoul Philharmonic. When his father opened a restaurant at the 1962 Seattle World's Fair, Myung-Whun came to the U.S. At 15 he was enrolled in the Mannes School of Music in New York and at 22, after touring with two of his sisters, entered Juilliard as a conducting major. Myung-Whun lives in L.A. with his wife, Sun Yol, 32, an interior designer who is expecting their first child next month. Since arriving in L.A. in 1978, he has lived up to his advance notices—and his name. Myung means "bright, shining like a star."
