The Empire State Building and the Statute of Liberty are among New York City's most prominent attractions. There are many others, but the one best beloved by both tourists and natives is Central Park, a verdant refuge from the teeming, ever-shaded concrete corridors that crisscross Manhattan. The 700-acre park with winding paths, undulating hills, carpets of flowers in spring -- equally resplendent with fall colors -- dotted with lakes, was America's first major metropolitan park. Visitors and residents owe it all to Frederick Law Olmsted, one of America's first, and certainly best-known, landscape architects. Although Central Park was his first project, the scope and breadth of his projects is nothing short of remarkable. In 1850, New York's population burst past 500,000, crowded into unsightly clapboard and brick tenements. Even the emerging middle-class had little room for recreation.
