The clock struck midnight on December 31, 1999 -- and for the first time in 1,000 years, all four numbers on the calendar changed. Time Magazine was there to record the great global celebration that ensued -- and to take the measure of the past millennium. This collector's edition from Time Magazine brings you unforgettable pictures of the world celebrating the dawn of a new century, from Sydney Harbor to Red Square to the Eiffel Tower. It includes Time's penetrating profile of the Person of the 20th Century -- Albert Einstein -- as well as runners-up Franklin D. Roosevelt and Mohandas Gahdhi. Lavishly illustrated, beautifully written, it is a keepsake to be treasured and passed on through the years.
