He has written many books and papers and received various 

 honors, chief of which was the 1907 Nobel prize in physics. He 

 died in May, 1931. 



Millikan. Robert Andrews Millikan is noted as an outstand- 

 ing experimenter. He was 

 born at Morrison, Illinois, in 

 1868. After his graduation 

 from Oberlin College, he con- 

 tinued his education at Co- 

 lumbia University and the 

 Universities of Berlin and 

 Gottingen in Germany. He 

 later joined the teaching staff 

 at the University of Chicago 

 where he became professor of 

 physics. In 1921 he became 

 director of the Norman 

 Bridge Laboratory of Physics 

 at Pasadena, California, and 

 chairman of the executive 

 council of the California Insti- 

 tute of Technology. 



Independent of his work as 

 a teacher, Dr. Millikan has 



done a great amount of scientific research. One of the problems in 

 which he became deeply interested was the nature of the electron. 

 He proved that all electrons are alike, and his observations of the 

 electron have been the most accurate of any yet made. He has 

 devoted a large amount of time to a study of the cosmic rays, a 

 little-known form of radiant energy, of unknown source, which 

 comes to the earth from somewhere in the space beyond our 

 atmosphere. 



Dr. Millikan was awarded the Nobel prize in 1923 for his work 

 in physical research. 



Einstein. One of the most famous of physicists is Albert 

 Einstein. Born of Jewish parents in 1879, his life up to 1933 was 

 spent in Germany and Switzerland. He spent his boyhood days 



Brown Brothers.
