Skier Andrea Mead Lawrence, winner of two gold medals in the 1952 Olympics, combines marriage and a career with notable success. Married to Dave Lawrence, onetime U.S. giant slalom champion, Andy Lawrence is now the mother of three children: Corty, who will be 3 in January, Matthew, 1�, and Deirdre, born this October. The Lawrences live on a 1,400-acre ranch in Parshall, Colo., and besides raising a family and Black Angus cattle, Dave and Andy also squeeze in some skiing. Last winter the Lawrences went to Aspen where Andy tuned up for a month before the Olympic trials at Stowe, Vt. At Stowe she made her comeback official with victories in the slalom and giant slalom and a tie for first in the downhill competition. At present Andy is in Italy, getting ready for the '56 Winter Games next month while Dave looks after the youngsters. Asked if the problems of long-distance motherhood are likely to affect Andy's chances, Dave replied, "Andy races purely against herself, and when she concentrates on a race everything else is shut off. She drives herself to do the best she can, and there's no reason why that should change."
