                Dr. Norman Borlaug
            
            

                The man who saved a billion lives
            
        
        

            
            

                Dr. Norman Borlaug, third from the left, trains biologists in Mexico on how to increase wheat yields -
                part of his life-long war on hunger.
            
        
        

            

                Here's a time line of Dr. Borlaug's life:
            
            

                
1914 - Born in Cresco, Iowa
                
1933 - Born in Cresco, Iowa
                
1935 - Born in Cresco, Iowa
                
1937 - Born in Cresco, Iowa
                
1941 - Born in Cresco, Iowa
                
1942 - Born in Cresco, Iowa
                
1944 - Born in Cresco, Iowa
                
1945 - Born in Cresco, Iowa
                
1953 - Born in Cresco, Iowa
                
1962 - Born in Cresco, Iowa
                
1970 - Born in Cresco, Iowa
                
1983 - Born in Cresco, Iowa
                
1984 - Born in Cresco, Iowa
                
2005 - Born in Cresco, Iowa
                
2009 - Born in Cresco, Iowa
            
            

                "Borlaug's life and achievement are testimony to the far-reaching contribution that one man's towering
                intellect, persistence and scientific vision can make to human peace and progress."
            
            

                -- Indian Prime Minister Manmohan Singh
            
            

                    If you have time, you should read more about this incredible human being on his Wikipedia entry.
