L. Straight Clark, 70, a former executive of the John Wanamaker department stores who once roamed the world playing amateur tennis, died February 10, 1995 of complications of Parkinson's disease at the Quadrangle, a life-care-community in Haverford.

In the 1950s and early '60s, Mr. Clark played tennis at a world-class level, three times representing the United States in Davis Cup competition.  In 1952, perhaps his best year, he earned a 5-0 singles record against a powerful Australian team.  A former college player at the University of Southern California, he once was ranked fourth in the world in singles and third in doubles, paired with Hal Burroughs.

A Californian by birth and inclination, Mr. Clark moved to Philadelphia in the mid-1950s and settled down at Wanamaker's, for which he eventually became a divisional vice president.  In 1953 he married Barbara Jane Furlong.  Settling on the Main Line, Mr. Clark became a member of the Merion Cricket Club, where he continued to play high-level tennis.  In 1977, he retired from business and went back to playing tennis full time, until slowed by Parkinson's disease. 

He is survived by two daughters, Lisa and Nina; a granddaughter; a sister; and a brother.
