CHAPTER XLV 

 FAMOUS SCIENTISTS 



A scientist discovers and perfects a serum for protec- 

 tion against a certain disease. In the years that follow, 

 its use saves thousands on thousands of lives. 



An inventor designs an odd-shaped glass bulb contain- 

 ing thread-like wires, and electricity banishes darkness. 

 Another works long days with wire, magnet and metal 

 disc. Suddenly we are able to talk with people far distant 

 from us. Others invent, and voices come to us from afar 

 through the air. What scientists discover serve the world. 



These scientific men and women, some unknown or lit- 

 tle known, have not spared themselves. They have labored 

 long and hard. Some have sacrificed fortunes and friends ; 

 others have given health and even life itself, that truths 

 might be discovered for the benefit of all. The roll of 

 scientists and inventors is a great honor roll. 



We have learned that much of the progress of the world has 

 been possible through the application of science. Back of this 

 progress is a whole procession of men and women, some of 

 whom gave their lives to learn more of the great truths that 

 underlie all scientific achievement. The story of their training 

 and life struggles, of their methods of work, and of their devo- 

 tion to science is a fascinating one. Even the brief glimpse given 

 here into the lives of a few of them should inspire all of us to 

 accomplish things worthwhile. 



Among the men and women who have done much to advance 

 science we find Francis Bacon, Galileo, William Harvey, Sir 

 Isaac Newton, James Watt, Michael Faraday, Joseph Henry, 

 James Prescott Joule, Louis Pasteur, Edward Jenner, Charles 

 Darwin, Joseph Lister, Alexander Graham Bell, Luther Burbank, 

 Thomas A. Edison, Madame Curie, Wilbur and Orville Wright, 

 Albert A. Michelson, Robert A. Millikan, Albert Einstein, Irving 

 Langmuir, and Arthur H. Compton.
