In 1978, Michael H. Hart published a book called The 100: A Ranking of the Most Influential Persons in History. It was a ranking of the 100 people who, in his opinion, most influenced human history. The book was hotly debated, and its concept widely copied. It is important to note that Dr. Hart is not ranking the greatest people. His criterion was influence.
The book was reprinted in 1992 with several notable revisions made to the original list of 100 people and their associated rankings. Chief among these revisions was the demotion of figures associated with Communism, such as Vladimir Lenin and Mao Zedong, and the introduction of Mikhail Gorbachev. Hart took sides in the Shakespearean authorship issue and substituted Edward de Vere, 17th Earl of Oxford for William Shakespeare. Hart also substituted Niels Bohr and Henri Becquerel with Ernest Rutherford, thus correcting an error in the first edition. Henry Ford was also promoted from the "Honorary Mentions" list, replacing Pablo Picasso. Finally, some of the rankings were re-ordered, while no one listed in the top ten changed position.

Hart admits that any assessment of historical significance depends on a perspective which only time can provide. To rate the historical importance of contemporary figures is almost impossible, while in other cases ranking will depend on an individual's assessment of the relative importance of the fields of scientific, cultural and religious endeavour.
Hart makes the point in the book where he points out that prior to the fall of the Soviet Union in 1991, Vladimir Lenin was ranked much higher on the list.
