Famous Scientists

By thorough, systematic study and experimenting, these men, 

 with very little early training, became modern scientists, whose 

 names stand high in the list of those who have made possible the 

 conquest of the air which is now an accepted fact. Until the 

 death of Wilbur Wright in 1912, their work was always done 

 together. 



Michelson. Dr. Albert A. Michelson, a native of Germany, 

 was born in 1852. When a child, he, with his parents, moved to 

 California where he prepared for college in San Francisco. He 

 later entered the United States Naval Academy from which he was 

 graduated in 1873, but continued there as an instructor in physics 

 and chemistry until 1879. During the years 1880 to 1882 he 

 studied at Berlin, Heidelberg, and Paris. On his return from 

 Europe, he was appointed to 

 the faculty at the Case School 

 of Applied Science at Cleve- 

 land, Ohio, and later at Clark 

 University, at Worcester, 

 Massachusetts. In 1892 he 

 went to the University of Chi- 

 cago to teach. 



Throughout his career Dr. 

 Michelson carried on research 

 work incessantly. His great- 

 est field of work was in light. 

 His measurement of the veloc- 

 ity of light is the most ac- 

 curate known. The methods 

 he used, as well as his equip- 

 ment, were of his own inven- 

 tion. 



During the World War he 

 returned to the naval service where several of his inventions, 

 especially a range finder, became regular naval equipment. 



After the war Dr. Michelson applied his knowledge of light to 

 the study of astronomy, and discovered a method for measuring 

 the diameter of stars.
