Explanation:
Albert Einstein   
(1879-1955) is considered by many the greatest astrophysicist and   
single most significant   
Person of the 20th Century.   
   
He is pictured here in the Swiss Patent Office where    
he did much of his defining work.     
   
Einstein's many visionary scientific contributions   
include the equivalence of mass and energy (E=mc^2),   
how the maximum speed limit of light affects measurements of time and space    
(special relativity), and a more accurate   
theory of gravity based on simple geometric concepts    
(general relativity).   
   
One reason   
Einstein was awarded the 1921   
Nobel Prize in Physics was to make the prize more prestigious.
